The correct answer is A. Voltmeter.
A voltmeter is an instrument used for measuring electric potential (voltage) difference between two points in an electric circuit. A voltmeter is an essential tool for electrical engineers and technicians, and is used in a wide variety of applications, from simple circuit testing to complex industrial control systems.
An ohmmeter is an instrument used to measure electrical resistance. An ohmmeter is typically used to test the condition of electrical components, such as resistors, capacitors, and inductors.
An ammeter is an instrument used to measure electric current. An ammeter is typically used to test the current flowing through a circuit, and to ensure that the current is within the safe operating limits of the circuit.
A wattmeter is an instrument used to measure electrical power. A wattmeter is typically used to measure the power consumed by an electrical device, such as a motor or a heater.
E is not a valid option.
