yes u r right and I read it in many books, internet ,videos but didn't get any thing in most of the books only the circuit diagram is explained but not why and how it happens , I have spent a whole month on semiconductor but till now I didn't understand much of it so I asked it here , I asked to another students also but they also knew only the book stuff

OK thanks

Glass transition ?

Why do chewing gum get stiff when we put water ( mainly cold ) on it ?

How do collector current is controlled by base current in a CE configuration transistor ?

How do that solid starch form I mean why it didn't just expanded like a bomb buy formed a solid 3-d structure

i think this may be the right reason

What do make a popcorn pop out like that it do ?

I have read that a single free neutron is unstable but then how a neutron star can exist ?

Whole 16 and 17 post

Till now I didn't studied the electronic s too much and I know only few of it therefore I didn't understand many of ur terms so please would u explain it in a simple language to me so that I can make my self to understand more of it

would u please explain it further like where it is positive and where to take negative by showing it in a circuit and thanks to u for understanding what I want to ask .

OK leave it I think I'm not getting it how to explain what I want to know but i know i dont want to know what you r thinking thanks for ur replies OK leave it I think I'm not getting it how to explain what I want to know but i know i dont want to know what you r thinking . thanks for ur replies

I didn't mean that I know that earthing of house hold appliances rather I wanted to ask the concept of earthing in small circuits like in a transistor http://101science.com/images/transistor.gif

What is the meaning of earthing of any circuit ,I know its a child question . everybody says that it means 0 potential at that point but I didn't understand it till now I mean how current will be flowing after grounding in a circuit , what is the use of it in circuit other than 0 potential , how is circuit is completed after it ? Please help me

But they don't have charge neither mass then how can they intrect

when ?

do two photons interact with each other ?

Why more energy flows through detritus food chain than grazing food chain

I have read that an electron and positron create two gamma photons after collision but is reverse also possible ?

that's what I want to say in a food chain cat come on next tropic level to cat ie a cat eats a rat but what if a rat eat a cat then in this case energy is flowed back word then is the rule voilated

Every ecologist knows flow of energy is unidirectional in an ecosystem , I tried to find its reason but didn't find any reasonable one so please help me .

would u please explain cooper loop more I tried it on internet but didn't understand

and what is it ?

QCD ?
