Why should an ideal or practical voltmeter have a very high internal resistance?
- 1To minimize the loading effect by drawing negligible current from the circuit✓
- 2To increase the total circuit current drawn from the source
- 3To increase the potential difference across the circuit elements
- 4To protect the voltmeter coil from damage due to high current
Correct answer
To minimize the loading effect by drawing negligible current from the circuit
