Battery/Cell explained simply : Chemical Energy driven charge pump.
Battery explained simply : Chemical Energy driven charge pump.
Description :
We can say battery is a charge pump which takes energy from the chemical energy of its constituents materials.
It pumps + ve charge from the -ve sphere to + sphere.
When the extranal circuit is not complete the pump stops and do no work.
When the external circuit is complete the + charge start moving from + sphere to -ve sphere and the pump also starts pumping more charge. Now it takes energy from the chemical energy of its contituents. As time passes the chemical enegry will keep reducing.
After sufficient time the energy will not be sufficient to run the pump and full rate or not run at all.
Then we say the battery is dead.
