Questions
In a series resonant LCR circuit, the voltage across R is 100 volts and R = 1 Kilo ohms with C=. The resonant frequency is 200 rad/s. At resonance the voltage across L is
a
2.5×10-2 V
b
40 V
c
250 V
d
4×10-3 V
detailed solution
Correct option is C
As it is in resonance i=vR=1001×103= 10-1A potentials VL=VC at resonance Vc= icω= 10-12×10-6×200=250Talk to our academic expert!
