An LCR series circuit with R = 100 Omega...

An LCR series circuit with `R = 100 Omega` is connected to a 300V, 50Hz a.c. source. If the capacitance is removed from the circuit then the current lags behind the voltage by `30^(@)`. But if the inductance is removed form the circuit the current leads the voltage by `30^(@)`. What is the current in the circuit?
