Question

when the diac has turned on, the voltage drop across its terminals is ______ the breakover voltage required to fire it.
○ the same as
○ greater than
○ less than

Explanation:

A DIAC is a bidirectional semiconductor device. Once it triggers (turns on) at its breakover voltage, it enters a low-resistance conducting state, causing the voltage drop across its terminals to drop to a much lower value, which is less than the breakover voltage required to initiate conduction.

Answer:

less than
