Detailed Solution
Download Solution PDFDIAC (diode for alternating current)
A DIAC is formed by connecting two diodes in an antiparallel manner. Hence, it allows the current to flow in both directions.
DIAC is used as the firing circuit for the SCR. Hence, it supplies a large gate current.
From the IV characteristics, it is observed that DIAC always conducts above the breakover voltage.
The correct answer is option 3.
