Calculate the voltage across the 6F capacitor.(a) 120V(b) 60V(c) 40V(d) 220VThe question was asked in unit test.I would like to ask this question from Distribution of Voltage Across Capacitors in Series topic in portion Capacitance and Capacitors of Basic Electrical Engineering

Answer» CORRECT option is (c) 40V

To EXPLAIN: Capacitors are in series.

1/C=1/2+1/4+1/6, therefore, C=(12/11)F.

Q = C*V = 220*(12/11) = 240C.

V ACROSS 6F capacitor = Q/C = 240/6 = 40V.
