Question

Potential diference between a live wire
and a neutral wizeis
150 Volt
210 Volt
220 Volt
200 Volt​

Answer 1

Answer:

Explanation:3 of them are phase conductors and one is neutral conductor, which is earthed near the transformer. So the potential of neutral conductor is zero. ... Hence the potential difference between live wire or phase conductor and the neutral, which is called the phase voltage is (415/ 1.732 i.e. root3) 240 volt and not 220.
