An A.C. circuit consists of an Indicator of inductance 0.5H and a capacitor of capacitance 8 muF in series. When the current in the circuit is maximum, what is the angular frequency of A.C. source ?

Answer»

500 rad/s
`2xx10^5` rad/s
4000 rad/s
5000 rad/s

Solution :`omega=1/sqrt(LC)`
`=1/sqrt(0.5xx8xx10^(-6))`
`=10^3/sqrt4`
`=1000/2`= 500 rad/sec
