Textbook Question
Chapter 60, Problem 1SQ
What are the three main electrical test instruments used in troubleshooting?
Expert Solution & Answer
To determine
List the three main electrical instruments that are used in troubleshooting process.
Explanation of Solution
Discussion:
Troubleshooting is a process in which the cause or source of the problem is to be determined by an electrician. If a control circuit is failed, the electrician determines the source of the circuit’s failure. The electrician can resolve the fault only after successful troubleshooting process.
The three main electrical instruments that are used in troubleshooting process by the electrician are as follows:
- Voltmeter
- Ohmmeter
- Ammeter
The voltmeter, ohmmeter, and ammeter measure the voltage, resistance, and current, respectively.
Conclusion:
Thus, the three main electrical instruments that are used in troubleshooting process are listed.
