Three capacitors of capacitances 3 μF, 10 μF and 15 μF are connected in series to a voltage source of 100V. The charge on 15 μF is
Options
(a) 500 μC
(b) 100 μC
(c) 200 μC
(d) 280 μC
Correct Answer:
200 μC
Explanation:
Equivalent capacitance = C
1/C = 1/3 + 1/10 + 1/15 = (10 + 3 + 2) / 30 = 15 / 30 = 1 / 2
⇒ C = 2 μF
Charge through each capacitor is same as they are joined in series.
Q = CV = 2 × 100 = 200 μC
