1 - Rectifier AC
1.1 - Power in electric circuits.
In the electronic circuits of devices such as Radio-Cassette, Amlpy, color TV, VCD, etc. ... we use a DC power at different voltage levels, but outside of the devices plugged Zac is back plugs directly into 220V 50Hz AC power, so the electronics needed to convert a part from AC to DC voltage supply for the circuit on, converters include:
