What is the difference between a bipolar transistor and a field effect transistor?
A bipolar transistor uses both majority and minority charge carriers for conduction, while a field effect transistor primarily relies on majority charge carriers. Field effect transistors have a higher input impedance compared to bipolar transistors. Additionally, bipolar transistors are current-operated devices, while field effect transistors are voltage-operated devices.

What is the difference between BJT and NPN transister?
Mainly there are two types of transistors. They are BJT (Bipolar Junction Transistors) and FET(Field Effect Transisters). In BJT, there are two types called PNP and NPN. Actually NPN means a BJT transister.
What is the difference between inotropic and cronotropic effect?
An inotropic effect refers to the ability to alter the force of muscle contractions, such as in the heart. A positive inotropic effect increases contractility, while a negative inotropic effect decreases it. On the other hand, a chronotropic effect refers to the ability to alter the heart rate. A positive chronotropic effect increases heart rate, while a negative chronotropic effect decreases it.
What is the difference between fet and ujt?
The structure of a UJT is quite similar to that of an N-channel JFET. The main difference is that P-type (gate) material surrounds the N-type (channel) material in case of JFET and the gate surface of the JFET is much larger than emitter junction of UJT.
What is the Seebeck effect?
The Seebeck effect is used in thermocouples. If two dissimilar metals conductors are joined and the two joints (junctions) are kept at different temperatures then a voltage is produced. This is dependant on the tyes of metals used and the temperature difference between the junctions. There is a reverse of the Seebeck effect called the Peltier effect where a current through the two different materials results in a temperature difference between the junctions.
What is the difference between electromeric effect and inductive effect?
Electromeric effect is the temporary effect involving complete transference of electrons and is concerned with pi-electrons while inductive effect which may be induced, timely induced or PERMANENT involves displacement of shared electron pair or tilt transference of electrons and moves through sigma-bonds.
Can fet be used as a transisitors?
No. The Field Effect Transistor is a different technology than the Bipolar Junction Transistor. That cannot substitute for one another.
What is bjt and jfet?
BJT is Bipolar junction transistor FET is Field effect Transistor It is a current controlled device It is voltage controlled device
Is Vcc notation used only in a transistor circuit?
Vcc is used in bipolar transistor circuitsVdd is used in field effect transistor circuitsB+ is used in vacuum tube circuits
What is another name for depletion mode transistor?
depletion layer depletion zone juntion region space charge region bipolar transistor field effect transistor variable capacitance diode
What is kirk effect?
The Kirk effect occurs at high current densities in bipolar junction transistors and causes a dramatic increase in the transit time of a transistor.
The control current of a transistor flows between which two terminals?
The control current of a transistor flows between the base and the emitter terminals in a bipolar junction transistor (BJT). In a field-effect transistor (FET), the control current is related to the voltage applied between the gate and the source terminals, influencing the current flow between the drain and the source. In both cases, the control current or voltage regulates the larger current flowing through the device.
What is the center section of a transistor called?
in bipolar transistors it is called the basein field effect transistors it is called the channel
What is semiconductor triode?
It can be either a Bipolar Junction Transistor (NPN or PNP) or a Field Effect Transistor (N channel JFET, P channel JFET, N channel MOSFET, or P channel MOSFET).
What can the input of a transistor be called?
The input of a transistor is typically referred to as the "gate" in a field-effect transistor (FET) or the "base" in a bipolar junction transistor (BJT). In both cases, the input controls the flow of current through the transistor, allowing it to function as a switch or amplifier in electronic circuits. The gate or base receives the input signal that modulates the transistor's operation.
What types of transistors are the following - BJT PCT UJT SBT FET GJT AJT DFT?
The BJT is the bipolar junction transistor, the PCT is the point contact transistor, the UJT is the uni-junction transistor, the SBT is the surface barrier transistor, the FET is the field effect transistor, the GJT is the grown-junction transistor, the AJT is the alloy-junction transistor, and the DFT is the drift field-junction transistor.
What is the difference between BJT and NPN transister?
Mainly there are two types of transistors. They are BJT (Bipolar Junction Transistors) and FET(Field Effect Transisters). In BJT, there are two types called PNP and NPN. Actually NPN means a BJT transister.
What is FET?
FET is abbreviation of Field Effect Transistor. This is a transistor in which current is controlled by voltage only and no current is drawn. It is a high input impedence device and is used in computers, telecommunication and control circuits. This transistor is better in certain parameters as compared to BJT, that is Bipolar Junction Transistor.
