Question

How can we protect the galvanometer?

Answer 1

Explanation:

Since we can protect a galvanometer by using a shunt resistor as shown in the figure.

1. The resistance is usually connected in parallel to a galvanometer to keep the resistance low.
2. This setup protects the galvanometer from strong or high amounts of currents.
3. With the low resistance, the value of the current that flows through the circuit is controlled effectively.

Hence, a galvanometer can be protected by using a shunt resistor.
