What happens if voltage is constant and current is varying when an scr triggers?

Even if the current is varying,as long as the current reaches the value required to trigger the SCR, it will snap into operation. The SCR will remain in operation until the current through it drops to a value below the holding current.

Constant voltage power supplies will maintain a constant voltage under varying?
current.
Can a transformer work with d.c.?
The primary coil has to induce current in the secondary coil. The only way this can happen is if there is a varying magantic field in the primary which then will induce a varying mag field in the secondary which results in a current in the sec. Only varying current can induce a varying mag field only a varying mag field can induce current So you need a varying current in the primary. D.C. is not a varying current so it cannot induce a mag field in the coil. A.C. (it does not have to be +/- it just has to be varying) can do so.
Can an object have varying speed if its velocity is constant?
no
Can a body have a constant but a varying speed and vice's?
no
What is the difference between constant rate and varying rate?
constant rate means that rate which is fixed and can not be changed. varying rate is that rate which is not fixed and can be change easily.
Can a body have a varying speed if its velocity constantif yes?
No, because constant velocity means constant speed and constant direction
What does ballast mean?
Electricity. Also called ballast resistor. a device, often a resistor, that maintains the current in a circuit at a constant value by varying its resistance in order to counteract changes in voltage. a device that maintains the current through a fluorescent or mercury lamp at the desired constant value, sometimes also providing the necessary starting voltage and current.
What is Difference Between Current Source and Voltage Source?
A current source varies the output voltage to maintain the desired current. A voltage source has a constant output regardless of the current draw (up to the capacity of the supply, of course).
Why ohms law is valid only for constant temperature and constant pressure?
Because by varying temperature ,the conductivity hence the resistivity varies so the constant varies.
What kind of systematic errors are detected by varying the sample size?
I believe a varying sample size detects a constant error which is a type of systematic error.
Can an object have a constant speed and the varying velocity at the same time explain?
Velocity is a vector. A vector has a magnitude and a direction. The scalar or magnitude portion of velocity is speed. Velocity is a constant only when both the speed and direction are not varying. Hence, when the speed is changing, the velocity cannot be a constant.
How can the frequency and voltage of an alternator be changed?
The frequency is changed by varying its speed, and the the voltage is changed by varying its field current.
