Why is it that while using a moving coil galvanometer as a voltmeter, a high resistance in series is required whereas in an ammeter a shunt is used?

Explanation

To understand why a high resistance is required in series with a moving coil galvanometer when used as a voltmeter, and why a shunt is used when it is used as an ammeter, we can break down the explanation into clear steps.

### Step-by-Step Solution:

1. **Understanding the Function of a Voltmeter**:
- A voltmeter is designed to measure the potential difference (voltage) across two points in a circuit. It is connected in parallel with the component across which the voltage is to be measured.

2. **High Resistance in Series with Voltmeter**:
