You build an electronic device to control a transistor switch that causes a mechanical device to push the switch. Now days we bypass the mechanical switch and the circuit can do the switching.

A transistor is a semiconductor device. It's purpose is to amplify and switch electronic signals and electrical power. Although it was developed during the early 1950s, it is the basic building block of much of our modern electronic equipment.

A transistor will either amplify a signal, or - more common in electronic circuits - work as a kind of switch, where one current can turn another current on or off.

I don't know which kind of switch, diode or transistor could act as. (I've missed that class). All I know is that a transistor is formed by two diodes. If any of them can act as a switch on a electronic circuit I think that a diode should be simpler to do that. Anyway, only an technical on electronics can give you the correct answer.

A transistor doesn't have any mechanical parts to wear out, so it will last longer. A transistor can switch much faster than a mechanical device, so they can switch all the way from DC up into the microwave region. It is physically small. Very handy. It allows a relatively small controlling current to switch very large controlled currents.

A Unijunction Transistor is a transistor that acts solely as a switch.

Transistor is an tiny electronic device called electronic switch,which is building block of a processor. Processor is a data processing device consists of thousands or millions of transistors. Eg- Intel 8086 microprocessor has around 29000 transistors.

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.

A: When a transistor is saturated current can flow in both direction qualifying it as a switch

it is a transistor used in IR TOGGLE SWITCH. :-)

transistor has 2 output 1 and 0 so can be used as a switch

Common emitter is the preferred circuit because the collector voltage drops to a well defined low value when the transistor is 'on', therefore it absorbs only a small amount of power.

User Avatar

Power transistor can conduct large amount of currents through it, more than small signal transistor. power transistor has a vertical structure and small signal transistor has horizontal structure.In power transistor quasi saturation region is present which is absent in the small signal transistor. In power transistor there is a inculsion of drift layer which is not there in the small signal transistor. Power dissipation is less in power transistor and it is more in small signal transistor. b.v.polytechnic,vasai pushkar vaity.

i imagine you are referring to ON as a transistor is saturated or ON.

Do you mean transistor? A transistor is a small low-powered solid-state electronic device, consisting of a semi conductor and at least three electrodes: emitter, base and collector. Fiifi Krampah.

Microchips and processors deal with electronic signals that vary. A transistor is used to switch between two different electronic signals and can also amplify the signals really quickly.

as the name suggest transistor means to transfer resistor, it is an electronic device,

Based on the application, a transistor can be used as a switch or a signal in a circuit.

An unbiased transistor is one being used with no bias voltage to offset its operating point. If the input signal is very small it still can operate as an amplifier but the output will be non-linear. One use for an unbiased transistor is when the transistor is used as a switch, turning it on or off.

A transistor is a small electronic device containing a semiconductor and having at least three electrical contacts, used in a circuit as an amplifier.

A transistor is a small electronic component with 3 pins coming out of the bottom. A transistor is used to redirect electric current. It can be controlled and made to redirect power to one location or another, and for one example of use, turn a light on and off with just a push button rather than a switch. They are only usable for small amounts of electricity (low voltages) so for high voltage (say 240V) you need a relay (google it if you don't know).
