1.	In a series LCR circuit the voltage across an inductor, capacitor and resistor are 20 V, 20 V and 40 V respectively. The phase difference between the applied voltage and the current in the circuit is (a) 30° (b) 45° (c) 60° (d) 0°
Answer» dAs voltage ACROSS inductance and CAPACITOR is same(series=>current is same)So inductive and CAPACITIVE reactances are equalRESONANCE CONDITIONThus the CIRCUIT acts as resistive circuit;where voltage and current are in phase.
