Question

The voltage disturbed from the main line to our house is usually an average of 240 volts AC. This is split into two with a common neutral wire, so that 120 volts AC is the voltage supplied from most ordinary socket outlets. But DC current is required for most electical appliances that are plugged into our sockets. No all appliances use the same voltage. Explain how this is achieved.

Explanation / Answer

The combination of step down transformer and recifier in an adaptor converts the AC to DC.

First the step down transformer reduces the AC voltage to the desired level .

Then the Rectifier converts the AC voltage to DC voltage to the home needs.
