Most electronic devices/circuits require dc-voltage to operate.
A battery is a good power source, however, its operating time is limited.
The use of battery also proves to be expensive.
A more practical alternative is to use the household main supply, and since this is an ac-voltage, it must be converted to a dc-voltage.
The circuit that converts this ac-voltage to a dc-voltage is called
A. rectifier
B. clamper
C. filter
D. regulator
