To charge a 1-F capacitor with 2 C requires a potential difference of:
A)0.2 V
B)0.5 V
C)2 V
D)5 V
E)none of these

Question

Quizplus · Accepted Answer

The formula for the capacitance is C=Q/V, where C is the capacitance, Q is the charge, and V is the potential difference. Rearranging this formula, we get V=Q/C. 
Substituting the given values, we get V=2 C / 1 F = 2 V. 
Therefore, the potential difference required to charge a 1-F capacitor with 2 C of charge is 2 V, making choice C the correct answer.
