In a series LCR circuit, the voltages across an inductor, a capacitor and a resistor are 30 V, 30 V, 60 V respectively. What is the phase difference between the applied voltage and the current in the circuit ?

Verified by Experts

If `phi` is phase difference between applied voltage and the current, then
`tan phi = (X_(L) - X_(C ))/(R ) = (I_(v) (X_(L) - X_(C )))/(I_(v) R)`
`= (V_(L) = V_(C ))/(V_(R )) = (30 - 30)/(60) = 0`,
`phi = 0^(@)`.
