If wattless current flows in the AC circuit, then the circuit is :

If wattless current flows in the AC circuit, then the circuit is :
  1. Purely Resistive circuit
  2. Purely Inductive circuit
  3. LCR series circuit
  4. RC series circuit only

Solution

The current in an AC circuit containing only either a capacitor or an inductor is said to be wattless as the average power is zero. As wattless current has phase difference of ϕ=90° with voltage, therefore power factor cosϕ will be zero.
