Question 1

1. How does power transformer work?

Answer 1

1. The high-voltage utility distribution wires transfer energy to the relatively low-voltage (240 V) wires connecting to our homes.
2. This 240 V secondary coil has a center top conductor that is grounded, and the voltage between it and either of the “live” ungrounded conductors is 120 V. This intentionally grounded conductor (the neutral) is designed to carry current all the time. It’s a “live” wire.
