PHY 102 Capacitors and Capacitance Objective Question

Question

What is the voltage across a capacitor immediately after the switch is closed in an RC charging circuit (assuming initially uncharged)?
Options
A V₀ (battery voltage)
B 0 V
Correct Answer
C V₀/2
D Depends on R
Correct Answer

Option B is the correct answer.

Detailed Explanation

At t=0, an uncharged capacitor behaves like a short circuit, so V_C = 0.

Hint

Initially uncharged → zero voltage.
