Hey guys can you help me out here...
I created a battery out of these materials
NH4Cl, MnO2, Zinc strips, carbon rod ...
What i did is make a 4 M solution of NH4Cl, by putting 20 grams of it into 85 ml of water... then I dipped a felt pad into it
Then I got 4 grams of the MnO2 and spread it onto the felt pad
Then I wrapped it around a carbon rod
Finally I covered the felt pad with multiple zinc strips ...
Finally I got an average of a 1.5 volt from this, using a voltmeter, yet when I connect it to a light bulb, it doesnt flash, but flashed from a 1.2 volt battery ...
Can anyone tell me why this happens ? ... Is it because the zinc strips are small... should it be one big piece ?
