It is a generator that transforms chemical energy into electric energy

A bulb transforms electric energy into luminous energy.

A resistor transforms electric energy into heat (thermal energy).

A push switch (button) is a momentary switch which causes a temporary change in the state of an electrical circuit only while the switch is physically actuated.

A buzzer transforms electric energy into a sound (acoustic energy).

A motor transforms electric energy into mechanical energy so it can do work.

A switch is used for closing and opening an electric circuit. Only when the circuit is closed, by switching it on, the current will flow.
