Q. In the circuit shown in figure, at resonance
UP CPMT
UP CPMT 2015
Alternating Current
A
the power factor is zero
8%
B
the current through the a.c. source is minimum
22%
C
the current through the a.c. source is maximum
60%
D
currents through $L$ and $R$ are equal
9%
Solution:
In the circuit shown $L$ and $C$ are in series. Therefore, it is a series resonance circuit Hence current through $a.c$. source is maximum
