Question

3. How much work is done in moving a charge of 2 C across two points having a potential difference of 12 V ?

Answer 1

We have to take potential difference as work done per unit charge to bring it from a point 0 to 12V.

                                                                                                                         Potential difference, V=12V

Charge=2C

V=W/Q

12=W/Q

W=24J

Hence, the work done in moving a charge of 2c across the two points having a potential difference is 12V is 24J.

Answer 2

Answer:

Work done is 24 J.

Explanation:

Given,

A charge of 2 C  moving across two points having a potential difference 12 V​.

To find: work done

Solution:

Work done can be found by the product of potential difference and charge,

i.e W = VQ

here, V = 12 V and Q = 2 C

Substituting the values,

W = 12 * 2

or, W = 24 J

Therefore, Work done is 24 J.
