In `LCR` circuit at resonance current in the circuit is `10 sqrt(2) A`. If tnow frequency of the source is changed such that now current lags by `45^(@)` that applied voltage in the circuit . Which of the following is correct.
A
Frequency must be increased and current after the change is 10 A
B
Frequency must be decreased and current after the change is 10 A
C
Frequency must be decreased and current is same as that of initial value
D
The given information is insufficient to conclude anything
