NCERT Solution Class X Science Electricity Question 3 (Ex 12.2)

Question 3:

How much energy is given to each coulomb of charge passing through a 6 V battery?

Answer:

The energy given to each coulomb of charge is equal to the amount of work required

to move it. The amount of work is given by the expression,

Work done = Potential Difference × Charges

Where,

Charge = 1 C

Potential difference = 6 V

Work Done = 6 × 1 = 6 J

Therefore, 6 J of energy is given to each coulomb of charge passing through a

battery of 6v.
