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 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.
How do you identify positive terminals in voltmeters and ammeters?
The positive terminals in voltmeters and ammeters are generally indicated by a red coloring and a + (plus) symbol. Negative is generally black and - (minus).
Difference between silicon-controlled rectifier and diode?
silicon controlled rectifier is a 3 terminal 4 layer device which has 2 consecutive P N junctions here the three terminals called anode, cathode and gate gate controls the conduction of the scr but diode just conducts in forward bias and blocks in reverse bias
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

What are the three terminals of a silicon bilateral switch?
Anode, Cathode and Gate. Like in a SCR
Can someone identify the terminals on a 1963 Corvette light switch?

How can you identify the positive and negative terminals on a Dell T6476 battery?
You can see it on the connection on the inside of the package.
Why SCR is not called GCR?
because it is gcr not scr

How do you identify the terminals of a 2N2222 BJT from datasheet?
See for example http://www.datasheets360.com/pdf/7308997814572458562 In general, terminals are identified by number and name, with reference to the physical appearance of the transistor package.

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.
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
