Question

How much work is done in moving a charge of 3 C across two points having a potential difference 9 V?

Answer 1

Answer:

27 Joules

Explanation:

V = W/Q

Voltage = Work Done per Coulomb (charged particle)

V = 9 V

Q = 3 C

W = Q × V

W = 9 × 3 = 27 J

Answer 2

Answer:

Given:

Potential difference (V)= 15 V

Charge (Q)= 3C

The potential difference(p.d) between two point in an electric circuit is defined as the amount of work done in moving a unit charge from one point to the other point.

Potential difference (V) = work done (W)/Charge (Q)

V= W/Q

Putting the values in the above formula we get:

15 V = W / 3 C

W= 15 V × 3 C

W= 45 J

Hence, the work done in moving the charge is 45 J.
