Question

Two capacitors of 0.5 μF and 1.5 μF capacitance are connected in parallel across a 110 V dc battery. The charges across the two capacitors after getting charged is ___________

(a) 55 μC each

(b) 275 μC each

(c) 55 μC and 275 μC respectively

(d) 275 μC and 55 μC respectively

I got this question in a national level competition.

My enquiry is from Advanced Problems on Network Theory in section Network Theory and Complex Circuit Diagram of Network Theory

Answer 1

The correct option is (c) 55 μC and 275 μC respectively

For explanation I would say: Q1 = 0.5 x 10^-6 x 110

= 55 μC.

Also, Q2 = 2.5 x 10^-6 x 110

= 275 μC.
