Which statement/statement is/are correct?
1. An ammeter is connected in series in a circuit and a voltmeter is connected in parallel.
2. An ammeter has a high resistance.
3. A voltmeter has a low resistance.

Explanation

To determine which statements are correct, let's analyze each statement one by one.

### Step-by-Step Solution:

1. **Analyze Statement 1**:
- The statement claims that "An ammeter is connected in series in a circuit and a voltmeter is connected in parallel."
- **Explanation**: This is true. An ammeter measures the current flowing through a circuit and must be connected in series to ensure that all the current passes through it. A voltmeter measures the voltage across a component and is connected in parallel to that component to measure the potential difference accurately.
- **Conclusion**: Statement 1 is correct.
