Question

On connecting a condenser in parallel to an electric fan connected to an AC circuit, the phase angle

• A. decrease
• B. increase
• C. remains constant
• D. keeps on increasing and decreasing

Answer 1

The correct option is A decrease

A condenser uses an inductor.
Inductor has the phase angle of$-{90}^o$ and resistor has phase angle of Zero.
So any combination of inductor and resistor gives a negative phase angle.
Initially phase angle was zero , finally its negative so, on connecting a condenser in parallel to an electric fan connected to an AC circuit, the phase angle decreases.
