When operated in cut off and saturation mode the transistor acts like what?
switch
How does a transistor electronically switch the output on?
A transistor can electronically switch the output by controlling the flow of current between its two terminals, called the collector and emitter. It has a third terminal, called the base, which acts as a control input. When a small current is applied to the base terminal, it influences the flow of current between the collector and emitter terminals, effectively turning the transistor "on" or "off" and allowing it to change the output state.
Which semiconductor acts like a diode and two resistors?
uni junction transistor
When transistor acts as an amplifier then does its output voltage increase or decrease?
That depends on both the input signal and the type of amplifier the transistor is used in.
The device which acts like an NPN and a PNP transistor connected base to base and emitter to collector is?
Triac
What is the purpose of the Unijunction Transistor?
A Unijunction Transistor is a transistor that acts solely as a switch.
When operated in cut off and saturation mode the transistor acts like what?
switch
Why a transistor acts as a switch?
Only because the circuit that its embeded in is designed that way. Remember, a transistor is basicly an amplifier ... only if you design everything to go to the extreams will it act as a switch.
What is transistor as a switch?
transistor is a nonlinear device. it will acts as a swicth based on the cut in voltage we can easily identifying the the transistor is in forward or reverse bias.in forward it is 'on' reverse bias 'off'.
What is the difference between nonlinear devices and linear devices?
In saturation region transistor acts as a non linear device i.e, there is no linear relation between input and output because in saturation region output does not change for variation in input. Whereas in other operating mode transistor acts as a linear device.
How transistor acts as a amplifier?
A transistor does not act as an amplifier. It is used as a component in an amplifier circuit.

How common emitter acts as a switch?
In response to the control signal on the base, the transistor switches on or off, effectively shorting the collector to the grounded emitter or opening leaving the collector floating.
Can a transistor can act like resistor capacitor inductor?
A transistor acts like a resistor when Gate is connected to Source.
What is the difference between linear and saturation regions in field effect transistor?
In the linear region, the transistor has an almost linear I versus V curve, which means that as you increase drain-source voltage, current changes proportionally, e.g. to a loose approximation, the FET behaves like a resistor, whose resistance is set by the gate-source voltage. In the saturation region, the I vs V curve looks like a horizontal line (almost) so it acts like more like a switch (neither of these analogies is exact, but they give the general idea).
When transistor acts as an amplifier then does its output voltage increase or decrease?
That depends on both the input signal and the type of amplifier the transistor is used in.
