its because it only allows current to passy through one direction. They are like diodes
uni junction transistor
No
That depends on both the input signal and the type of amplifier the transistor is used in.
switch
Transformers are inherently bidirectional.
A Unijunction Transistor is a transistor that acts solely as a switch.
A transistor does not act as an amplifier. It is used as a component in an amplifier circuit.
uni junction transistor
A transistor (bipolar junction transistor BJT) will only conduct in ONE DIRECTION. And the voltage drop is not Ohmic - it is *NOT* strictly related to current flow. If you're referring to a Field-Effect Transitor (JFET, IGFET, MOSFET, etc), then the device may be able to be used in a bidirectional circuit. But the question stated "transistor", which is understood to be a BJT.

A transistor acts like a resistor when Gate is connected to Source.
No
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'.
That depends on both the input signal and the type of amplifier the transistor is used in.

Relays are bidirectional devices.
