The breakover voltage can be adjusted to a value that is less than the original value if no zener diode were to be used, but it cannot be adjusted to a higher value.

Question

Quizplus · Accepted Answer

The breakover voltage is the voltage at which a zener diode starts to conduct. If no zener diode is used, the breakover voltage is the voltage at which the transistor starts to conduct. This voltage can be adjusted to a lower value by using a resistor in series with the transistor, but it cannot be adjusted to a higher value.
