JAMB - Physics (1997 - No. 32)
If 8 x 10\(^{-2}\) J of work is required to move 100\(\mu\)C of charge from a point X to a point Y in an electrical circuit, the potential difference between X and Y is
4.0 x 102 v
4.0 x 104 v
8.0 x 102 v
8.0 x 10-2 v
Explanation
V = \(\frac{W}{Q}\)
V = \(\frac{8 \times\ 10^{-2}}{100 \times\ 10^{-6}}\)
V = 8.0 x 10\(^2\) v
V = \(\frac{8 \times\ 10^{-2}}{100 \times\ 10^{-6}}\)
V = 8.0 x 10\(^2\) v
