Question

What is the function of galvanometer in the circuit?(All India - 2019)

Answer 1

Answer:

Galvanometer is used to check the presence of current in the circuit.

Answer 2

The function of Galvanometer in the circuit is to detect the presence of electric current in a circuit.

Explanation:

• The primary function of the galvanometer is used for detecting the presence of electric current in a circuit.  
• It is actually an instrument for measuring the current by the deflection of the moving coil. The deflection is derived from the forces resulting from the current.
• Galvanometer works on the principle of magnetic effects of electric current.
• If there is a current in the circuit, the needle in the galvanometer will show deflection.This indicates the presence of current in the circuit.
