On what basis the third terminal of a transistor is given name base?

In the original point contact transistor design, there was a base of semiconductor material at the bottom to which two point contact wires were connected, each point contact wire being very close to the other on the surface of the base. There were three wires, one to each of the point contacts and one to the semiconductor base. The two point contacts were called the collector and emitter, and the base was called - logically, being at the bottom - the base.
We tend to show the base as being between the collector and emitter, but in actuality the collector and emitter were added on top of the base.
Although all modern bipolar transistors are junction transistors, the standard bipolar transistor symbol is actually a point contact transistor symbol, although the base may be drawn on any side not just the bottom.

What is the usage of third terminal in transistor?
There are three terminals on a transistor. Some have four, where the fourth is a screen.The normal three are Emitter, base and collector. The Emitter emits electrons, the collector collects them and the base controls the flow.
How does a transistor electronically switch the output on?
A transistor can electronically switch the output by controlling the flow of current between its two terminals, called the collector and emitter. It has a third terminal, called the base, which acts as a control input. When a small current is applied to the base terminal, it influences the flow of current between the collector and emitter terminals, effectively turning the transistor "on" or "off" and allowing it to change the output state.
What is the third terminal on electric equipment?
The third terminal connects to earth ground.

What is the best way to describe the function of a typical transistor in an electronic circuit?
A transistor in a circuit can do many things. It can be used to amplify voltage signals, or current signals, create current and voltage sources, make buffers, and so on. Transistors also find a major use in logic circuits (ie, where signals can either be a '0' or a '1'), where they essentially act as a switch, and can be used to create inverters, AND gates, OR gates, and all sorts of useful components. By itself, a transistor is a three-terminal device that can control the current going through two of its terminals through the voltage applied at the third terminal. But there are many applications for a transistor in its many different configurations, which is why it is so important in modern electronic technology.
What is a resistor and a transistor?
there is 2 types of componant 1-passive compnant:who provide a fixed voltage to active componant we can not use them in rectification or amplification,registor,capacitor,inductor 2-active componant:we can use its as a amplifier r rectifier,diode,transistor,scr,etc (we can use registor for voltage drop,so it is passive componant)
How does a transister work as an amplifier?
The name is your clue: a transistor and a resistor (the load) are put in series. The output signal is taken from the load resistor. A small input signal (to the third lead of the transistor) will cause the transistor to change resistance ... thus you can get a large output from a small input Amplification.
What is the meaning of third terminal of mobile phone battery?
The third terminal is a communication between the battery electronics and the mobile phone, it is like a one wire communication to tell the mobile phone the state of the battery etc.
On what basis can the government regulate the rights of assembly and petition?

What is working principle of rheostat in electric circuits?
The basic principle that rheostats use is Ohm's law, which states that current is inversely proportional to resistance for a given voltage. This means the current decreases as the resistance increases or it increases as the resistance decreases. Current enters the rheostat through one of its terminals, flows through the wire coil and contact, and exits through the other terminal. Rheostats do not have polarity and operate the same when the terminals are reversed. Three-terminal potentiometers can be used as rheostats by connecting the unused third terminal to the contact terminal.
Why do you not get battery symbol on your laptop sometimes after you on power supply in your laptop made by Toshiba model no A200?
Note: When interconnecting A200 batteries (cells), they must be identical in voltage and amp rating! Batteries may be connected in series. The positive terminal of the first battery is connected to the negative terminal of the second battery; the positive terminal of the second is connected to the negative of the third, and so on. The voltage of the assembled battery is the sum of the individual batteries. The batteries are connected: + to - to + to - to + to -, etc. The capacity of the battery is unchanged. Batteries may also be connected in parallel. The positive terminal of the first battery is connected to the positive terminal of the second battery, the positive terminal of the second is connected to the positive of the third; the negative terminal of the first battery is connected to the negative terminal of the second battery, the negative terminal of the second is connected to the negative of the third and so on. The batteries are connected: + to + to + and - to - to -. In this configuration, the capacity is the sum of the individual batteries and voltage is unchanged.
