Question
Two capacitors of 6 F and 3 F are connected in series with a potential difference of 12 V. Find the p.d. across the 6 F capacitor.
Correct Answer
Option D is the correct answer.
Detailed Explanation
Series combination: 1/C = 1/6 + 1/3 = 1/2, C_total = 2 F. Total charge Q = C_total V = 2x12 = 24 C. Voltage across the 6 F: V = Q/C = 24/6 = 4 V.
Hint
Series combination: 1/C = 1/6 + 1/3 = 1/2, C_total = 2 F.
