The voltage regulation of synchronous generator operating at a leading power factor is

The voltage regulation of synchronous generator operating at a leading power factor is:

1. Negative
2. Positive
3. Zero
4. None of these

Correct answer: 1. Negative

Explanation:

The basic formula for voltage regulation is:

VR = (V_nl – V_fl)/ V_fl

For leading power factor the full load voltage (Vfl) is higher than the no-load voltage (Vnl) and thus the voltage regulation is negative.
