A voltmeter is a device that
- draws high current
- has a very low resistance
-
has a very high resistance
- is able to measure both voltage and current
The correct answer is: C
Explanation
A voltmeter is a device used to measure the voltage across two points in an electrical circuit. To achieve accurate measurements without interfering with the circuit's operation, a voltmeter is constructed with:
Very High Resistance
This high resistance limits the current drawn from the circuit, allowing the voltage measurement to be taken without altering the conditions of the circuit.
