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

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

Options

  1. APurely Resistive circuit
  2. BPurely Inductive circuit
  3. CLCR series circuit
  4. DRC series circuit only

Correct answer

B. Purely Inductive circuit

Step-by-step 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°ϕ = 90 ° with voltage, therefore power factor cosϕcosϕ will be zero.
