Question

what amount of work is needed in moving 2c charge through a potential differences of 8v​

Answer 1

Answer:

we know,

w = qv

= 2×8

= 16J .....ans.

Answer 2

Given:

Charge(Q) = 2c

Potential difference (V) = 8v

To Find:

The amount of work needed in moving 2c charge through a potential difference of 8v

Solution:

Work done refers to the energy consumed by a charge for moving through a potential difference

This can be summarized by the formula:

work done = charge × potential difference

W = Q × C

We know that,

Q= 2c

V= 8v

Put the given values in the above formula to find the work done:

(no need to convert values as they are already si units)

W = 2 × 8

W = 16

The unit of work done is Joules (J)

Work done = 16J

Hence, 16J of work is needed in moving 2c charge through a potential differences of 8v.
