SCR or Silicon Controlled Rectifiers are Bipolar junctions Transistor ( Thyristor Family), SCRs are made of two transistors thats why they PNPN or NPNP devices.
The three important parts of transistor are - Emitter, Collector & Base.
& the Three Important parts of SCR are - Anode, Cathode & Gate.
Use of SCRs- rectification of high power AC & power control applications, such as lamp dimming, regulators and motor control.
Use of Transistors - switch, audio, high voltage, amplifiers, switcher

What is the difference between an SCS and an SCR?
An SCS has an additional gate - the anode gate. It is physically smaller than an SCR and has smaller leakage and holding currents than an SCR.
2 transistor analogy for scr and derivation for expression of anode current?
a thyristor can be considered as two complementary transistors , one pnp- transistor, and other npn transistor
What is the difference between npn and pnp transistor in the application?
There is no difference they perform the same functions.
What is the difference between capacitor and transistor?
transistor either increase or decrease current bt capacitor stores the energy
What is the difference between an SCR and a TRIAC?
A thyristor is another name for an SCR, which stands for Silicon Controlled Rectifier.Thyristors or SCRs are bi-directional devices used to control the flow of AC current. Once triggered, the device remains "on" until the next wave of current crosses zero after the trigger is removed.For more information about thyristors or SCRs see the Related link shown below.

Why doesn't an SCR switch off once it turns on even after reducing gate potential?
A thyristor or silicon controlled rectifier (SCR), as they are sometimes known, consists of two transistors. A pulse on the gate turns on the second transistor which then turns on the first transistor in the combination. Turning on the first transistor enables anode current to flow and maintains a base current for the second transistor which keeps it on.See the Related link for an equivalent circuit for an SCR or thyristor.

Describe the difference between SCR and SCS?

What is the difference between a diode and scr?
A diode mainly consists of only 2 terminals(anode,cathode).A SCR mainly contains one more terminal called GATE.The main purpose of the gate in an SCR is just to provide pulses.The main draw back of SCR is it is not fully controllable device.
Where does a SCR differ from a power transistor in operation?
thyristor can be scr or triac scr is strictly dc a triac is back to back scr's with a common gate two scr's back to back can be gated independently scrs cost less than triacs an scr can be combined with a full wave bridge to make an equivalent to a triac but this gives an additional 1.5V forward voltage drop
What is the difference between transistor and processor?
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.
Difference between NPN and PNP?
NPN and PNP are transistor types. The difference in the way the layers of semiconductor material are doped with impurities.
What is the difference between a switching transistor and an ordinary transistor?
In the switching transistor the output current is controlled by the (current) and this is also called current controlled current device (CCCD). But in ordinary switch we controlled output current physically...
