What is the shape of a transistor?

What is the shape of a transistor?

Transistors are manufactured in different shapes but they have three leads (legs). The BASE – which is the lead responsible for activating the transistor. The COLLECTOR – which is the positive lead. The EMITTER – which is the negative lead.

Is a transistor a BJT?

A bipolar junction transistor (BJT) is a type of transistor that uses both electrons and electron holes as charge carriers. BJTs use two junctions between two semiconductor types, n-type and p-type, which are regions in a single crystal of material.

How do I choose the right transistor?

When choosing a transistor to use as a switch you need to consider its maximum collector current Ic(max) and its minimum current gain hFE(min). Transistor voltage ratings may be ignored for supply voltages less than 15V.

Which is the best description of a transistor?

A transistor is a type of a semiconductor device that can be used to both conduct and insulate electric current or voltage. A transistor basically acts as a switch and an amplifier. In simple words, we can say that a transistor is a miniature device that is used to control or regulate the flow of electronic signals.

How are the legs of a transistor different?

TWO EXAMPLES OF DIFFERENT SHAPES OF TRANSISTOR Transistors are manufactured in different shapes but they have three leads (legs). The BASE- which is the lead responsible for activating the transistor. The COLLECTOR- which is the positive lead. The EMITTER- which is the negative lead.

What are the terminals of a field effect transistor?

For a field-effect transistor, the terminals are labeled gate, source, and drain, and a voltage at the gate can control a current between source and drain. The image represents a typical bipolar transistor in a circuit. Charge will flow between emitter and collector terminals depending on the current in the base.

Is the transistor a switch or a switch?

Transistors can be regarded as a type of switch, as can many electronic components. They are used in a variety of circuits and you will find that it is rare that a circuit built in a school Technology Department does not contain at least one transistor.
