Which semiconductor acts like a diode and two resistors?
uni junction transistor
The device which acts like an NPN and a PNP transistor connected base to base and emitter to collector is?
Triac
How transistor acts as bidirectional?
its because it only allows current to passy through one direction. They are like diodes
What does the base do in a transistor?
It depends on the transistor, you just have to look at the data sheet for the transistor.
What does a transistor look like?
Transistor is a three terminal device. Its shape may differ with applications.
Can a transistor can act like resistor capacitor inductor?
A transistor acts like a resistor when Gate is connected to Source.
Which semiconductor acts like a diode and two resistors?
uni junction transistor
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).
What are the importance of transistor?
A transistor is a semiconductor(like many) that amplifies and switches electrical signals(electronic switch) in a circuit, it is used inside a circuit which requires switching without been manually operated.
The device which acts like an NPN and a PNP transistor connected base to base and emitter to collector is?
Triac
How transistor acts as bidirectional?
its because it only allows current to passy through one direction. They are like diodes
What should be the value of collector current in terms of DC gain if transistor is in saturation mode?
DC current gain is collector-emitter current divided by base-emitter current. In linear mode, gain is beta, or hFe. In saturation mode, however, the transistor is over-driven and you can no longer relate collector-emitter current to base-emitter current. The transistor operates like a switch, and collector-emitter current is a function of voltage and load impedance only. (Ignoring the relatively small voltage drop.) To maintain saturation mode, the collector-emitter current must be smaller than the base-emitter current times hFe. Often, it is several times smaller, because hFe can vary from transistor to transistor, and your design must account for this variability.
What happens when emitter and collector of a transistor are short?
The transistor acts like a normal pn diode. in NPN transistor the both n i.e.,collector and emitter ane shorted then they become a n and other is p so pn diode is formed. When the emitter and the collector of a transistor are short, the emitter current =the collector current.
What does the base do in a transistor?
It depends on the transistor, you just have to look at the data sheet for the transistor.
The transistor acts like a diode and?
Yes, the transistor acts like a diode. That is, essentially, what it does. What it also does, and what give it its added value and ability to amplify, is that the base current causes the collector-emitter "diode" junction to vary in its turn-on characteristic. With this ability, you can control a large current with a small current, and a small delta-current in the base causes a larger delta-current in the collector, the ratio being hFe, hence the term "gain".
What are the characteristics of saturation?

Is a diode like a transistor?
No. A diode is not like a transistor, and a transistor is not like (two) diode(s). Taken in isolation, the emitter-base and collector-base junctions of a transistor appear to be diodes, but they are coupled together so that the base-emitter current affects the collector-emitter current.
