Questions
A series R-C circuit is connected to an alternating voltage source. Consider two situations:
(a) When capacitor is air filled.
(b) When capacitor is mica filled. Current through resistor is i and voltage across capacitor is V then
detailed solution
Correct option is D
Current through resistor, i = Current in the circuit =V0R2+XC2=V0R2+(1/ωC)2 Voltage across capacitor, V=iXC=V0R2+(1/ωC)2×1ωC=V0R2ω2C2+1 As CaTalk to our academic expert!
