In a certain series RLC circuit it is found that at resonance,
the inductive reactance is equal to the resistance. It is also found
that rms current in this circuit at resonance was
[IMAGE]. If now angular frequency of source is doubled
without changing any other parameter, what will be new rms current in
ampere in circuit?

Show answer and solution
At resonance:
[IMAGE] Atangular frequency of source is double of resonance frequency:
[IMAGE] TOPIC:Alternating current
SUB TOPIC:RLC circuit
