Which is a type of in-circuit component test?

In-circuit component testing is essential for troubleshooting electronic circuits and assessing the health of individual components while they remain connected within the circuit. Each of the listed tests—voltage, current, and resistance—plays a vital role in this process.

Performing a voltage test allows technicians to measure the voltage level across a component or circuit node, indicating whether the device is receiving the correct supply voltage and functioning as expected. A current test, on the other hand, measures the flow of electric current through the circuit, which can help identify issues such as short circuits or overly high current that may indicate a fault condition. Lastly, a resistance test evaluates the resistance of a component, enabling the detection of opens or shorts in circuit paths.

Since each of these tests provides valuable information about the operational status of components within a circuit without the need to remove them, they collectively represent the comprehensive approach of in-circuit testing. Therefore, the correct choice encompasses all these testing methods as integral parts of in-circuit component testing.
