.....

There is an electric current from the top terminal of the battery to the bulb through wire 1. but no current back to the base of the battery' through wire 2, since the current is used up lighting the bulb. The electric current is in the direction shown, but there is less current in the return wire (wire 2). since some of the current is used up lighting the bulb. There is an electric current in both wires 1 and 2 in a direction from the battery to the bulb. The electric current is in the direction shown, and the magnitude of the current is the same in both wires I and 2.Which model do you think best describes the current through the bulb? Explain

Explanation / Answer

model D decribes best the current throguh the bulb, as there exists a flow of chsarge from + ve terminal to -ve termimal

by the time the charges reaches the -ve terminal, they are left with minimum energy, here the source of emf does an external work on the charges to make them to move formt he region of low potnetial to high potentia;

and again once the charegs reaces high potential , (+ve charge) they tend to move from high pot tp loe potential via bulb and current passes through bulb continuously
