Question

A375 p_F capacitor is connected in series with an unknown capacitor, and as a series combination they are connected to a24.0 V battery. If the 375 p_F capacitor stores 78o p_c of charge on its plates, what is the unknown capacitance?

Answer 1

Solution In series connection, both capacitor store same amount charges the amount of chargein unknown capacitoris 0-V,C 1 thepotential at this capacitor would be 1 C+C

now the capacitance of unknown c apacitor is, сут (C+C2) since^, - C1 780x10-12 С 375x10-12 F - 2.08 V 240V-2.08 v375x10F) 2.08 V 24.0V- 2.08 V 35.6x10-12c -35.6pC
