Question

Battery do not provide charge but in denial cell zn converted zn±by one election which results in flow of current does this mean battery provide charge tell me sir ormam

Solution

A battery maintains a nearly constant change in electric potential across its terminals. When a complete circuit is connected from one terminal to the other, there is an electric current. Of course this current isn't for "free". It takes energy to move this current through a circuit. Where does the energy come from? There is energy stored in the battery in the form of chemical potential energy.

Yes, it is true that a current can be described as moving electrical charges. However, it is not true that these charges are "stored in the battery". Let me give a simple analogy. If electric current is like water, then a battery is like a water pump.

So in Daniel cell is provding energy for prodution of currrent by conversion of Zn into Zn2+ by release of electrons.

So we can see that even though battery does not store charge ,it provide energy for flow of electrons and thus produce current..
