How is electricity produced in a wet cell?

Answer 1

The gravitational and electrical pootential are quite similar . Like a difference in the gravitaional potential causes the movement of the mass to a lower potential point simmilarly in an electric field a charged particle also has an electric potential or electric potential field simmilar to a mass has in a gravitational field . Suppose a negatively cahrged object and a positive test charge is placed near it then as we all know that the positive test charge will be attracted towards the negatively charged object . Now if we want to move tha +ve test charge away from the negatively charged object them we will have to spend some energy and that energy will get converted into the electric potential energy . This means that we did do some work in in moving that +ve test charge away from the -ve sphere and spent energy in doing so . Thus its electric potential enrgy increased . Thus there is some electric potential difference between the the two points - the initial pont and the second point . This potential difference will cause the test charge to move to the initial point and the electric potential energy will get converted into kinetic energy or useful work . Thus now we know that a potential difference is required to move the charge . If a charged body is connected to an uncharged body by a conductor then charge will flow from the charged to the uncharged body . This means the charge will flow from the high potential(charged body) to the low potential (uncharged body). A dry cell provides current and to do so it maintains a potenial difference . By the chemmical reactions taking place in the dry cell the charges are maintained on the respective electrodes and hence a potential differnce is maintained which causes the elctrons to flow when the cell is connected to a load . I normal AA cell has a standard potential difference of 1.5 volts which means 1.5 joules of energy is carried by every 1 coulombs of the charge and this energy is used in the load to produce power . Gradually the chemicals get used up and the cell gets discharged .

Answer 2

it is produced by radiation of sunlight..
