Question
When operated in cutoff and saturation, the transistor acts like a
(a) Linear amplifier
(b) Switch
(c) Variable capacitor
(d) Variable resistor
Solution
When a transistor is operated in cutoff and saturation, it acts like a (b) Switch.
Here's why:
-
Cutoff Mode: In this mode, the transistor is in "off" state or it is cut-off. This means no current flows through it. This is similar to the "off" state of a switch.
-
Saturation Mode: In this mode, the transistor is in "on" state or it is saturated. This means maximum current flows through it. This is similar to the "on" state of a switch.
So, when a transistor is operated in these two modes, it behaves like a switch, turning on and off.
