Questions
In the adjoining figure, four capacitors are shown with their respective capacities and the P.D. applied. The charge and the P.D. across the capacitor will be.
detailed solution
Correct option is D
Total capacitance 1C=120+18+112⇒C=12031μFTotal charge Q=CV=12031×300=1161μCCharge, through 4μF condenser =11612=580μCand potential difference across it =5804=145 V.Talk to our academic expert!
