What is the meaning of transistor in processor?
It is used in the control logic and for representing controlled data. Basically a transistor has two inputs where one of the inputs decides whether or not to output the other. Imagine you have a vacuum cleaner. If the vacuum cleaner is on then the following two conditions are met: 1. The cable is connected to the wall. 2. You have the switch in on position. These two conditions represent the two inputs in the transistor (both being "on" if you can hear your vacuum cleaner). The output is represented by whether or not the vacuum cleaner is on. The switch decides whether or not to let whatever electrical signal you may have through to the vacuum cleaners engine. If switch is on then it outputs the signal from the cable. If the cable is not connected there will still be an output but it will be an "off". Sorry about the potentially confusing analogy.
How do you wire a DPST switch?
A double pole single throw switch. used to switch two lines at the same time.
How diode can be used as switch?
No, a diode can rectify an AC signal but is not able to amplify an AC signal. Diodes are two layer devices whereas transistors have three. It is this very thin 'base' region in the transistor that gives it the ability to give a voltage or current gain.
The metal lead of p type of one pn diode connected to the metal lead of p type of another pn diode makes a npn transistor?
No. You cannot create a transistor by connecting two diodes together. There is an interaction between the junctions of a transistor, said interaction being not possible when two diodes are connected together.
How is the NPN transistor different from the PNP transistor?
"P" is for Positive and "N" is for Negative So basically put a PNP Transistor Would use N to Switch P, in the name "PNP" or "NPN" the first character is for the polarity of the Collector-pin, the second for the Base-Pin, and the third for the Emmiter-pin. So if you have a PNP Transistor you can`t just replace it with an NPN as the polarities differ. If you can find a way to change those polarities then sure it could work. The Collector-pin basically receives the bigger current. The Base-pin determines how much of that current will be transferred to the emmiter-pin. So in a PNP the base current could for example be 0V and the Collector 5V, this will allow a free flow of current from Collector to Emmiter, the usage of a transistor in many cases is to switch high current with lower current. The main difference is that a PNP transistor uses "holes" as carriers and an NPN transistor uses electrons as carriers (It is to be remembered that the flow of current is always in the direction opposite to that of the flow of electrons). The difference in the symbol for the two transistors are that the PNP transistor will have an arrow pointed to the base from the emitter, and the NPN has it pointing outside.
When atrasistor is used as aswitch in what two states is it operated expiain with the help of diagram?
When a transistor is used as a switch, it operates in two states: the "ON" state (saturation) and the "OFF" state (cutoff). In the "ON" state, the transistor allows current to flow through it, effectively acting as a closed switch. Conversely, in the "OFF" state, the transistor prevents current flow, acting like an open switch. A simple diagram illustrating this would show the transistor symbol with labels for collector, base, and emitter, alongside a current flow path in the ON state and no current flow in the OFF state.
How many states does a switch have?
A switch has two states, on and off.

Can you use diode in place of a transistor?
no,we cant use transistor by combination of two diodes because we will come across a condition called current hogging.it means large amount of current flows through the device,diode can just rectify the signal but not amplifies it. Transistors however, can be used as diodes.
How does a npn transistor switch work to switch a load on and off?
let's insert a transistor in place of the switch to show how it can control the flow of electrons through the lamp. Remember that the controlled current through a transistor must go between collector and emitter. Since it is the current through the lamp that we want to control, we must position the collector and emitter of our transistor where the two contacts of the switch were. We must also make sure that the lamp's current will move against the direction of the emitter arrow symbol to ensure that the transistor's junction bias will be correct as in Figure below(b).
Which is better as a switch diode or transistor?
Basically a diode is a combinstion of pN junction but the transistor is made with three terminals EMITTER,, BASE ,, JUNCTION.. and diode is just a combination of positive and negative terminal . diode and transistors are both used as a switch .. but a transistor is more widly udes than a diode. and diode has also very important in electronics DIGITAL SYSTEM to make the screen's ..and transistors are used in amplifiers the group of transistors make an amplifier . and we use a diode in seven segment display ....diode is small and carry less current due to its small size but transistor get large current. A2 A diode has two connections. It allows current to flow in one direction and not in the other. They are used for rectification in power supplies, detection of AM radio, blocking of current etc. A Transistor has three connections. Current is controlled between the emitter and collector, by a small current on the base. They are used as switches, amplifiers and regulators.
What is darlington configuaration?
A Darlington pair uses two transistors connected to behave as a single transistor with a very high current gain (beta). Transistor-1 has its collector connected to the collector of transistor-2. Transistor-1 has its emitter connected to the base of transistor-2. The base of transistor-1 with the emitter and collector of transistor-2 is used as a single transistor.
Why a transistor acts as a switch?
Only because the circuit that its embeded in is designed that way. Remember, a transistor is basicly an amplifier ... only if you design everything to go to the extreams will it act as a switch.
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.
