Statement I: At resonance, 
series circuit have a maximum current.
Statement II: At resonance, in 
series circuit, the current and emf are in phase with each other.
In the light of the above statements, choose the most appropriate answer from the options given below.
Text Solution
Verified by ExpertsD
Both Statement I and Statement II are correct.
At resonance 
or 
. Because of this impedance of 
series circuit become equal to resistance of circuit 
. Therefore from 
, at resonance, current in 
series circuit is maximum correspondingly phase angle is also equal to zero. Therefore emf and current are in phase in 
series circuit.
