A charge of 10 C is transferred across a potential difference of 220 V. Determine the work done.
22J
2200J
210J
230J
Correct answer is B
The work done in moving a charge across a potential difference is given by the formula W = QV, where W is the work done, Q is the charge and V is the potential difference. Substituting the given values, we get W = 10 C * 220 V = 2200 J. Hence, the work done is 2200 J.
