Problem
An AC series circuit has XL<XC. Which one of the following correctly states the nature of the phase angle ϕ between the supply voltage and current in its phasor diagram?
(a) ϕ is zero and the current is in phase with the voltage.
(b) ϕ=−90∘ and the circuit behaves as a pure capacitor.
(c) ϕ is negative and the current leads the voltage.
(d) ϕ is positive and the current lags the voltage.
