What are three terminals?
Its three terminals are usually designated as MT1 (Anode 1), MT2 (Anode 2), and the gate by G as in a thyristor. When in operation, a Triac is equivalent to two SCRs connected in antiparallel. As the Triac can conduct in both the directions, the terms anode, and cathode are not applicable to Triac.
How will you identify the three terminals of transistor?
In plastic casing, one side of the transistor is Flat which is the front side and the pins are arranged serially. To identify the pins, keep the front flat side facing you and count the pins as one, two etc. In most NPN transistors it will be 1 (Collector), 2 (Base) and 3 ( Emitter ). Thus CBE.
What are the three terminals of BJT?
The BJT (bipolar junction transistor) is a current-controlled electronic device main employed for amplification and switching purpose. It comes with three terminals called emitter, base, and collector. The small current at the base side is used to control the large current at the remaining terminals.
Why does a transistor have 3 terminals?
BJTs have three terminals, corresponding to the three layers of semiconductor—an emitter, a base, and a collector. They are useful in amplifiers because the currents at the emitter and collector are controllable by a relatively small base current.

What are the three transistor configuration?
The three types of configurations are Common Base, Common Emitter and Common Collector configurations. In every configuration, the emitter junction is forward biased and the collector junction is reverse biased.
What type of transistor is BC547?
BC547 is a Bipolar Junction Transistor, abbreviated as BJT. It is an NPN transistor. It has three terminals named as: Emitter.
What are the three terminals of Mosfet?
Typically, the MOSFET is a three-terminal device with gate (G), drain (D) and source (S) terminals. Current conduction between drain (D) and source (S) is controlled by a voltage applied to the gate (G) terminal.
Which terminal of a transistor is the output terminal?
In common base configuration, emitter is the input terminal, collector is the output terminal, and base is the common terminal.
What is input characteristics of transistor?
The input characteristic of a transistor is obtained between the inputs current IB and the input voltage VB by having a constant output voltage VCE. By keeping the output voltage VCE constant and changing the input voltage VBE of different points, we can examine the values of the input current of each of the points.
What are the three regions of a transistor?
A bipolar junction transistor (BJT) has three operating regions:
Cut off ( for NPN BJT)
Active region ( for NPN)
Saturated ( for NPN)
What are the 3 terminals of a transistor called?
A transistor is an electronic device that contains three terminals named emitter, base, and collector. The small current at one terminal is used to generate a large current at the remaining terminals. Transistors are mainly employed for switching and amplification purposes.
What are the four transistor circuits?
Cut-off — The transistor acts like an open circuit. No current flows from collector to emitter. Active — The current from collector to emitter is proportional to the current flowing into the base. Reverse-Active — Like active mode, the current is proportional to the base current, but it flows in reverse.
What are 5 devices that transistors are used in?
Transistors are also found in pacemakers, hearing aids, cameras, calculators, and watches. Most of these devices draw their power from tiny batteries. Most spacecraft also rely on microchips, and thus transistors.
Which of the following device has three terminals?
The transistor is a three-layer, three-terminal device.
How many terminals does a BJT have?
The Bipolar Junction Transistor (BJT) is a current controlled valve. The 3 terminals are named base, collector and emitter.
What are the 3 BJT configurations?
The three basic configurations of a BJT are (a) common emitter (CE), (b) common base (CB), (c) common collector (CC) or emitter follower. These basic configurations are shown in Figure 1.
What are types of transistor configuration?
Generally there are three different configurations of transistors and they are common base (CB) configuration, common collector (CC) configuration and common emitter (CE) configuration. The behavior of these three different configurations of transistors with respect to gain is given below.
What are the components of a transistor?
There are typically three electrical leads in a transistor, called the emitter, the collector, and the base—or, in modern switching applications, the source, the drain, and the gate.
What is PNP and NPN transistor?
NPN and PNP refer to the arrangement of the pieces that make up the transister. An NPN transistor has a piece of P-type silicon (the base) sandwiched between two pieces of N-type (the collector and emitter). In a PNP transistor, the type of the layers are reversed. Below is a typical cross section of a transistor.
How does current flow through a transistor?
We know that in transistors and diodes, electric current is carried by both free electrons and holes. Free electrons and holes travel in opposite directions. For example, if free electrons flow from left to right then the holes will flow from right to left.
How do you identify the base terminal of an NPN transistor?
Keep the positive probe to the pin-1 (Emitter) of the transistor. Touch the negative probe to the center pin (Base). You will see some voltage in the multimeter. Similarly touch the negative probe to the center pin (Base) with respect to the pin-3 (collector).
Is BC547 transistor NPN or PNP?
BC547 -> BC547 is a NPN transistor hence the collector and emitter will be left open (Reverse biased) when the base pin is held at ground and will be closed (Forward biased) when a signal is provided to base pin.
Why is BC547 used?
BC547 is usually used for current amplifier, quick switching and pulse-width modulation (PWM). Therefore, if you need to control the speed of a motor or actuator in some of your projects, you can simply use this transistor to achieve it.
How does BC547 transistor works?
The BC547 transistor is an NPN transistor. A small current of the base terminal of this transistor will control the large current of emitter and base terminals. The main function of this transistor is to amplify as well as switching purposes. The maximum gain current of this transistor is 800A.
How do you identify a transistor?
To help identify them, transistors are labeled with number and letters on their casings. Transistors are labeled according to the numbering system that is used. The primary numbering systems are JIS, Pro Electron, and JEDEC.
What are two-terminal devices?
For any two-terminal device, such as a resistor, capacitor, diode, battery, etc., a full useful description of its operation is given in some form which relates the current through the device to the voltage across it. Such a relationship is expressed in various ways.
When transistors are used in digital circuits they usually operate in the?
Therefore, when transistors are used in digital circuits, they usually operate in saturation and cut off regions and option (D) is correct.
