Question

i. Calculate the potential difference between the two terminals of a battery, if 100 joules of work is required to transfer 20 coulombs of charge from one terminal of the battery to the other.
​

Answer 1

Answer:

V=W/q so potential = 100/20 which is equal to 5volts

Answer 2

Answer :

Work required to transfer charge = 100J

Amount of charge = 20C

We have to find potential difference between terminals of battery$.$

⧪ Work done to move a charge of magnitude q from one point at potential V₁ to another point at potential V₂ is given by

• W = q × ∆V = q × (V₁ - V₂)

⭆ W = q × ∆V

⭆ 100 = 20 × ∆V

⭆ ∆V = 100/20

⭆ ∆V = 5volt
