Question
We know that the amplitude of oscillating system becomes maximum, when the applied frequency is equal to the intrinsic frequency of system. And this concept can be applied even in electrical a.c circuits containing 
and 
It is being such that when the frequency of broad casting station becomes equal to frequency of radio circuit, then the impedance (equivalent resistance) of circuit becomes minimum and maximum current flows in the circuit with the result the radio station is tuned its impedance is given by
and 
Now in the given circuit as shown, at a certain moment of the values of voltages and current are given When power loss through resistor is 50 watt, then angular frequency of applied a.c voltage is
