A voltmeter is a device that:
C. has a very high resistance
Explanation:
A. draws high current: This is incorrect. A voltmeter is designed to draw as little current as possible to avoid affecting the circuit being measured.
B. has a very low resistance: This is incorrect. A voltmeter should have a very high resistance to ensure it does not affect the circuit or alter the voltage being measured.
C. has a very high resistance: This is correct. A voltmeter has high resistance to ensure that it draws minimal current and measures the voltage accurately without significantly affecting the circuit.
D. is able to measure both voltage and current: This is incorrect. A voltmeter measures only voltage, while an ammeter measures current.
Thus, the voltmeter's high resistance is crucial for accurate voltage measurements.
C is the right option here
A Voltmeter is used to measure potential difference between two point in an electric circuit. simply put, it is used to measure voltage. It has a very high resistant.
