A Silicon Controlled Rectifier - also known as a thyristor - is a diode with an added terminal whereby, by applying a "control voltage", the diode can be turned "on" but never "off".
When supplied with alternating current an SCR or thyristor will always turn off whenever the current falls back to zero in every cycle.

In the case of a computer file, it's the extension type .scr used for a screen saver.
What else can I help you with?
What is the basic function of the SCR's gate electrode?
The SCR's gate electrode is used to turn the SCR on, i.e. fire it.
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
How can an SCR be made to conduct?
An SCR has three legs. The anode, cathode, and gate. The control voltage sent to the gate will allow the SCR to conduct.
How to identify scr terminals?
Scr looks like a regulator IC. So keep the scr in such a way that its name should face us. then from left it will KAG.
What happens if gate voltage of an ON scr is decreased?
A: Nothing after an SCR conduct the gate has no more control to shut it off. So how do we shut off an SCR two way reverse the voltage on the SCR or reduce the current below the holding current. SCR are not DC friendly once on they stay on until see above
What is the basic function of the SCR's gate electrode?
The SCR's gate electrode is used to turn the SCR on, i.e. fire it.
What is the firing angle of silicon controlled rectifier?
The SCR turns on based on gate voltage. The firing angle will depend on the point in the AC cycle where the gate voltage is where you want it, so the firing angle is a function of circuit design, not of the SCR.
Why SCR is not called GCR?
because it is gcr not scr
What is Clutter improvement factor?
Clutter Improvement factor is defined, formally, as the ratio of output SCR to input SCR which works out to be a product of clutter attenuation and signal gain. It is a measure of a systems rejection capabilities of clutter power as a function of Doppler frequency.

What is the calculation for changing the firing angle in scr-?
The calculations for changing the firing angle in SCR is K = 1 [π − α + 1 sin(2α )]
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.
What is SCR a abbreviation for as in SCR brick?
'Structural Clay Research' is the name on record for the patent of this brick.
Application of light activated scr?
where do apply ligt activated scr, please diagram example.
