PHY 102 Last Minute Prep Objective Question

Question

What is the relation between current and voltage in a capacitor?
Options
A I = (1/C)Vdt
B I = C(dV/dt)
Correct Answer
C I = (1/C)(dV/dt)
D I = Ct
Correct Answer

Option B is the correct answer.

Detailed Explanation

The current through a capacitor is proportional to the rate of change of voltage across it: I = C (dV/dt).

Hint

How does current relate to the change in voltage in a capacitor?
