Which of the following is not the use of a shunt?

To increase the range of voltmeter

The correct answer is Option (2) → To increase the range of voltmeter

A shunt is a low-resistance path used to bypass most of the current around a galvanometer to protect it and extend its range.

Uses of a shunt:

✅ Prevent galvanometer from damage due to large current

✅ Convert a galvanometer into an ammeter

✅ Increase the range of an ammeter

❌ Increasing the range of a voltmeter is **not** done using a shunt (it uses a series high resistance instead)

Answer: To increase the range of voltmeter
