Solution

The four essential components of an electric circuit are power source, wire, bulb and switch. An electronic circuit is a structure that sends the electrical signal and also controls electric current to perform various functions including signal amplification, computation, and data transfer. It comprises several different components such as resistors, transistors, capacitors, inductors, and diodes. There are many types of power source. The most common one is dry battery, storage battery and generator, etc. The function of a power source is to convert chemical energy into electric energy
