Question

Flow of electrons through a wire is known as current. Battery has to do a work for this. Then work done by the battery in sending five hundred electrons through the resistor R in given circuit diagram is:

(A)-1.44 x 10-15 J

(C) 1.44 x 10-15 J

(B)-4.8 x 10-16 J

(D) 4.8 x 10-16 J​

Answer 1

Answer:

The power source moves the existing electrons in the conductor around the circuit. This is called a current. Electrons move through a wire from the negative end to the positive end. The resistor uses the energy of the electrons around the wire and slows down the flow of electrons.
