Are transistors still used today?
Of course. Transistors are the base of all computer processors. They are the successor to the vacuum tube.http://en.wikipedia.org/wiki/Transistor
What elements are used in transistors?
Silicon and germanium are the elements used in transistors
What are power transistors?
Power transistors are transistors that are used in high-power amplifiers and power supplies.
What does the arrow in bipolar junction transistor symbol represent?
There a two types of bipolar transistors PNP and NPN . This refers to the doping elements used in the silicon components of this 3 layer device with base always in the middle. The arrow is the emitter wire and shows direction of conventional current flow(positive to negative) NPN transistors (generally used in negative earth circuits) have the arrow pointing away from the base connection PNP transistors ( generally used in circuits with positive earth) have the arrow pointing towards the base connection.
What are transistors used in?
Transistors are used in any electrical somponent including amplifiers, remote controls etc.
What element are in transistors?
Silicon and germanium are the elements used in transistors
What elements in in transistors?
Silicon and germanium are the elements used in transistors
What are PNP and NPN?
In most discrete bipolar junction transistors the substrate is the collector. In monolithic integrated circuits the bipolar junction transistors are electrically isolated from the substrate, either by reversed biased junctions or insulator (e.g. sapphire). Some older bipolar junction transistor types (usually made with germanium) the substrate is the base. In bipolar point contact transistors the substrate was the base.
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
Why are npn transistors used more often than pnp transistors?
The primary reason that NPN transistors are used more often than PNP transistors is that they usually operate faster (at higher frequencies) because the mobility of the current carriers in NPN transistors (electrons) is much higher than that of the current carriers in PNP transistors (holes).
Why transistors are not used for switching devices?
Transistors are used for switching devices! What gave you the idea they aren't?
What is the emitter base collector in 2N5777 photo transistors?
1st pin is emitter then collector and base
