An inductor of inductance L, a capacitor of capacitance C and a resistor of resistance R are connected in series to an ac source of potential difference V volt as shown in figure.Potential difference across L,C and R is 40 V,10 V and 40 V, respectively. The amplitude of current flowing through L-C-R series circuit is 102 A. The impedance of the circuit is :

Options:

Answer:
C
Solution:

V=VR2+VC-VL2

=402+(10-40)2

=50 volt

irms=VrmsZ

⇒  Z=vrmsirms

⇒  Z=Vrms×210

⇒Z=2×50102

⇒Z=5 Ω
