Voltage accross parallel electric circuits.

flame vt. to criticize harshly, usually via an electronic medium.

 

No, I did not flame, I do not flame, and I will not flame. Alternative terminology can create an intellectual barrier between the few people who might use it and the rest of the world. Here's a few examples:

 

1. Anilkumar wants to check the outflow of his battery. What setting does he use on his multimeter?

 

2. Anilkumar goes to the store, shows the clerk his batteries and tells him that he thinks that he has the wrong batteries for his new short-wave radio and that he wants ones with more outflow. What change in battery characteristics should the clerk recommend?

 

3. Anilkumar is in electronics class, and his teacher asks a question about a problem in their textbook. Anilkumar answers it by saying that there seems to be an outflow imbalance in the circuit. His teacher asks him to explain. What does Anilkumar tell the teacher?

Well, I have another opinion of that and you fail miserably in convincing me otherwise, since you insist on repeatedly continuing to attack my wording, even after that I already have, more than once, admitted there might be language problems and that I didn't use the correct terminology.

 

Furthermore and most important in this stupid argument of the correct usage of words, why did you not answere my question of which is more important, terminology or working principle? Do you or do you not admitt that understanding of the working principle is more important?

 

 

Alternative terminology can create an intellectual barrier between the few people who might use it and the rest of the world.

I agree that it is helpful if people use the same terminology and there could be problems when someone doesn't, but usually it can be solved with a friendly conversation instead of a bashing, if people are willing to try.

 

Also, you seem to neglect that I actually did explain my wording in post #21.

 

 

Here's a few examples:

I don't know what to make of your examples, they seem wrong:

 

1. Anilkumar wants to check the outflow of his battery. What setting does he use on his multimeter?

A person who doesn't understand the working principle and then connects the multimeter wrongly could damage both the battery and the multimeter, while getting hurt to boot. Also if someone already have a basic understanding on the working principle and what they want to measure then they know both how to connect the multimeter and what settings they should use. Knowledge of whether potential is measured in voltage, current in amperes and resistance in ohms is less important.

 

2. Anilkumar goes to the store, shows the clerk his batteries and tells him that he thinks that he has the wrong batteries for his new short-wave radio and that he wants ones with more outflow. What change in battery characteristics should the clerk recommend?

If someone already know the basics and have made the conclusion that a different battery characteristics is needed then they already know why and which battery to use instead. Asking a random clerk in a random store of which batteries to use for a new short-wave radio will likely not lead to any good advice at all, from my experience you are lucky if you find someone able to translate from a LR6 to AA size. If you on the other hand ask a clerk that is a specialist with good knowledge, then all you have to know is what equipment you need the battery for.

 

3. Anilkumar is in electronics class, and his teacher asks a question about a problem in their textbook. Anilkumar answers it by saying that there seems to be an outflow imbalance in the circuit. His teacher asks him to explain. What does Anilkumar tell the teacher?

The only student in the electronics class that is going to be able to explain a phenomena to the teacher is the one with knowledge of the working principle, someone spouting from ignorance and randomly inserting technical terminology words are not going to make any sense at all.

Now if you truly are worried about people reading my explanation and getting "intellectual barriers" then you yourself should answere and explain the question in the OP with the correct technical terminology. That way you would contribute positively to this thread in a helpful manner instead of repeatedly attacking my wording.

So, here's a very simple example:

 

1. What multimeter setting does Spyman use to check the outflow of his batteries?

I am sorry ewmon, but I don't know what to make of this example either, can you please explain whats new with it?

 

Because both your intentions and my explanations has already been covered from post #21.

Okay, here's one part of your post #21 that mentions outflow (and the only other instance is similar to this one) ---

 

In layman's terms: "the battery's maximum outflow is higher than what the load can consume".

 

... the load will have a current flow through it ... that is lower than what the battery is able to sustain.

You mention "outflow" and "current flow", so do you mean that outflow is current? So, people should use a current setting on their multimeters to measure outflow? Is this correct? It seems that the answer can be a simple "Yes" or "No". I think this will settle it. Thanks.

While I partly choosed the word "outflow" to visualize a stream of water pouring out from the battery, like in the analogy were water relates to the current, that is not all I had in mind or the whole truth.

 

A battery is a containter were energy is stored, this energy gets transferred to the equipment and gets consumed. The correct technical terminology for the the rate at which energy is flowing out from the battery or getting consumed is Power, which is measured in Watt and is defined as one joule per second.

 

In direct current resistive circuits, electrical power is calculated using Joule's Law: Power = Voltage * Current

 

I have seen more advanced multimeters able to measure power directly but most standard multimeters don't have a setting for this and as such depending on circumstances two multimeters might be needed.

 

If the battery is in good shape and not overstrained such that it is able to keep its voltage stable then it is enough to know the voltage and measure the current or if the load is a simple like a resistor or at least stable then it's enough to know the impedance and measure the voltage, the other unit can be calculated from Ohm's Law.

 

But when the battery is close to empty or under excessive strain, the voltage will drop fast and if the load is fluctuating like for an amplifier connected to a loudspeaker were the amplitude and frequency of the sound changes rapidly, then both the voltage and current needs to be measured simultaneously.

Hi Spyman & Ewmon,

 

Clash of the titans?!

 

A lot of information poured out. So ultimately science wins. Good for science.

 

Nice explanation there.

 

I knew right from the begining; that the "outflow" you mentioned was [in layman's terms] the ability of the battery to deliver. And that has to be, power [technically]. Because, in the analogy of water falling from above and hitting the water wheel, even if one single water molecule falls on the wheel; it is falling from the same altitude. So has to give the rated reading. But it is unable to move the wheel because, of less number of molecules. If the wheel is to move, only the altitude is not sufficient. The number of molecules is also an important player. Similarly in the electrical analogy, in a depleted battery, even one single electron flowing through the circuit has to give the rated voltage reading [if you have the apropriately sensitive Voltmeter]. But that single electron can not do your job of heating the filament of a bulb for example. You need more electrons flowing through it. So the voltage and the current together do the job. Voltage and corrent put together is POWER.

 

I was tempted to bring up the equivalent technical word for "outflow" to Ewmon's notice. But I had to be patient as I was not the authority, to answer. Now Spyman, after knowing that my understanding of your explanation is right, I felt I should endorse it.

 

But Spyman,

 

a few more doubts have cropped-up in my mind, due to your posting No- 21 & 23. But I will post them in my next posting. Right now I am chewing it.

 

Thanks and regards.

It's good to see that we didn't manage to scare you away with the quibbling, take your time and when you are ready post your questions.

Hi,
