Chapter 4, Problem 1RQ
What are the three most common electric meters used in the industry?
Expert Solution & Answer
To determine
The type of three most commonly used electric meters in the industry.
Explanation of Solution
An electric meter is a device utilized to measure various electrical variables or characteristics of a circuit. The most commonly used electric meters are listed below:
- Ammeter –– Used to measure the current flowing in an electric circuit. There are two types of ammeters.
- Voltmeter –– Used to measure the potential difference between two specific points in a circuit.
- Ohmmeter –– Used to measure the resistance of the component associated in a circuit.
