Question

How to calculate potential difference in a circuit?

Answer 1

Answer:

Explanation:

Potential difference is the work done in moving a unit charge.

Thus, Potential difference (V) = Work (W) / Charge (Q)

[I derived this from W = QV]

Work (W) = Potential difference (V) × Current (I) × Time (t)

Power (P) = V × I
