Question

calculate the p.d b/w two terminals of the battery if 100j of work is required to transfer 20 c of charge from one terminal to other

Answer 1

the potential difference is 5 Volts

Answer 2

Given :

Work required (W) = 100 J

Charge (Q) = 20 C

To Find :

Potential difference between two terminals of the battery

Solution :

Work required in moving the charge = Potential Difference × Charge

∴ Potential Difference between the terminals of the battery =  $\frac{Work}{Charge}$

Here, Work (W) = 100 J and Charge (Q) = 20 C

So, Potential Difference    =   $\frac{100}{20}$

                                           =  5 V

Therefore, the potential difference between two terminals of the battery is found to be 5 V.
