Question

State the functions of each of the
following components in an electric
circuit:
a. Galvanometer b. Key​

Answer 1

Explanation:

Galvanometer, instrument for measuring a small electrical current or a function of the current by deflection of a moving coil. The deflection is a mechanical rotation derived from forces resulting from the current.

The circuit is called 'closed' when the current flows in the circuit, and when the current does not flow, it is called an 'open circuit'. The switch or key helps to make or break the circuit, i.e. switches on or switches off the current.

Answer 2

Answer:

A galvanometer is an electromechanical instrument used for detecting and indicating an electric current. A galvanometer works as an actuator, by producing a rotary deflection of a pointer, in response to electric current flowing through a coil in a constant magnetic field.
