A diode circuit used to protect a sensitive circuit is called a ________.
A) fuse
B) rectifier
C) filter
D) limiter

Question

Quizplus · Accepted Answer

A diode limiter circuit is used to protect a sensitive circuit from voltage spikes or surges. The diode limits (or clips) the voltage to a safe level that the sensitive circuit can handle. Fuses are also used for protection, but they are not specifically diode circuits. Rectifiers and filters are used for converting AC to DC and smoothing out the DC output, respectively, but they are not used for protection purposes.
