Why do you use a transistor?
Transistor is a semiconductor device used for amplify and switch electronic signals and electrical power. It is composed of semiconductor material with at least three terminals for connection to an external circuit.
What is functions transistors?
Transistor amplify and switch electrical power and electronic signals. These are made of semiconductor material with three or more terminals used to connect to an external circuit.
What are the three categories of materials used in electronics?
insulator, conductor and semiconductor
What are the types of polarization?
electronic polarization ionic or atomic polarization orientation or dipole polarization space charge polarization
What is the diode and Why it is used in electronic circuits?
A diode is basically a electronic non return valve it let current flow in one direction only and can not be used for amplification it only consist of a cathode and anode, where the transistor can be used in many applications, for instance as an amplifier, electronic switch, oscillator etc. it consist of three connections eg. Collector, Emitter and a Base normally the current is collected at the Collector and emitted at the Emitter and the Base is used to control the current flow with the Base at 0 volt no or very little current will flow between C and E it will only switch on with the B at about 2.7volt and the higher the B voltage the more current will flow thru the transistor
What is the term for an electronic components composed of three layers of a semiconductor material?
Transistor.

What does a tarnsistor do?
A transistor is a small electronic device containing a semiconductor and having at least three electrical contacts, used in a circuit as an amplifier.
What does NPN and PNP stand for in transistors?
A transistor is a three-terminal device consisting of 3 layers of semiconductor material. Two of them are one type of semiconductor and the third, a different type. For example, a PNP transistor consists of 2 layers of P-type semiconductor and a layer of N-type semiconductor between them. We can also have the NPN type transistor which has 2 layers of N-type semiconductor and a layer of P-type semiconductor between them. The three terminals are respectively referred to as emitter, base and collector. Transistors are widely used electronic components that perform the function of a switch or an amplifier. The semiconductor material used in transistors is generally silicon, germanium or gallium arsenide. Impurities are added to them in order to create electrically positive (P) or electrically negative (N) behavior. When these layers are joined together the contact potential creates a potential barrier across the PN or NP junction. This potential barrier maintains electrons on the N side and holes on the P side. NPN stands for negative positive negative PNP stands for positive negative positive. GALLIUM ARSENIDE is only used on LEDS manufacturing not transistors ANSWER: NPN negative positive negative SUBSTRATE PNP is opposite of NPN
What is a UJT?
UJT(UNIJUNCTION TRANSISTOR) is a three-lead electronic-semiconductor device with only one junction that exclusively as an eletrically controlled swtich andit is not used as a linear amplifier.
What is functions transistors?
Transistor amplify and switch electrical power and electronic signals. These are made of semiconductor material with three or more terminals used to connect to an external circuit.
What does a transister look like?

What is meant by gun diode?
A Gunn diode, also known as a transferred electron device (TED), is a form of diode, a semiconductor electronic component, used in high-frequency electronics. Its internal construction is unlike other diodes in that it consists only of N-doped semiconductor material, whereas most diodes consist of both P and N-doped regions. In the Gunn diode, three regions exist: two of them are heavily N-doped on each terminal, with a thin layer of lightly doped material in between. When a voltage is applied to the device, the electrical gradient will be largest across the thin middle layer. Conduction will take place as in any conductive material with current being proportional to the applied voltage. Eventually, at higher field values, the conductive properties of the middle layer will be altered, increasing its resistivity, preventing further conduction and current starts to fall. This means a Gunn diode has a region of negative differential resistance. Its largest use is in electronic oscillators to generate microwaves, in applications such as radar speed guns and microwave relay transmitters
