it says in neutral wire current flows under normal condition,
but when we put tester it wont glow, why?
Answer Posted / vikram
Tester glows between phase & earth, when the circuit is completed through our body to earth. But since the neutral & earth are solidly earthed on Transformer secondary side so the neutral serves as earth, though the current in neutral is there because of imabalance in phaes.
