4. an scr can be tested by using ____________\na. an ammeter.\nb. a voltmeter.\nc. a curve tracer.\nd. an ohmmeter.

Answer

Brief Explanations:

A curve - tracer can display the voltage - current characteristics of an SCR, which helps in testing its functionality. An ammeter measures current, a voltmeter measures voltage, and an ohmmeter measures resistance, but they are not the best for comprehensively testing an SCR.

Answer:

C. a curve tracer.
