|
|
Wattmeter
|
|
|
Wavemeter

Explanation:
Detailed explanation-1: -Voltmeter: A voltmeter is used to measure the difference in electric potential between two points. Voltmeters have high resistance and are connected in parallel to the electrical component whose potential difference is being measured.
Detailed explanation-2: -Measurements in Circuits **Voltmeters: **Voltmeters measure the potential difference (voltage) between two points in a circuit. For example between two points either side of component X above. Voltmeters must always be connected in parallel (on a separate branch of the circuit) with the two points being measured.
