They need to use- well the best thing/object/equipment for them to use is a voltmeter!

Is the open circuit voltage of a solar cell measured under non-illuminating condition?
Well, you should really measure the open-circuit voltage and the short circuit current both under dark and light conditions and then compare them to fully characterize a solar cell. Measuring the open-circuit voltage means measuring the voltage across the cell when no current is flowing (i.e., with a LARGE resistance as a load on the cell). Measuring the short-circuit current means measuring the current when the voltage across the circuit is essentially zero (i.e., with a VERY SMALL resistance as a load on the cell--thus, "short-circuit" current).
Which is preferred for measuring emf of a cell avoltmeter or potentiometer?
A voltmeter is used to measure voltage. A potentiometer is used to vary the amount of resistance in a circuit - it has nothing to do with measuring.
What instrument used for measuring the voltage difference?
A VoltMeter
Is line voltage or phase voltage mentioned on transformer nameplate?
It depends how they are connected. If they are connected between line conductors then they are measuring line voltages. If they are connected across phases then they are measuring phase voltages.
What is core magnetic balance test of transformer?
magnetic core balance test is used to find out the flux distribution. It can conduct either in HV side or LV side. In HV side, applying voltage between 2 phases and measuring the voltage across other phase.(eg.applying b/w U&V, and voltage b/w V&W , W&U measuring.) In LV side, applying voltage b/w any phase....and measuring voltage across other phases. Result: sum of measured voltage will be equal to applied voltage.

What is end cell voltage?
end cell voltage
Unit for measuring voltage?

What is the difference measuring in volts?
Voltage
What is an electrolytics cell?
A cell with a negative voltage charge.
When measuring voltage the probes should be connected in?
can some one please tell me when measuring voltage the probes should be connected to sequence or series?
How does the technique for measuring current with DMM differ from measuring voltage?
current is measured with the meter in series and voltage is measured with the meter in parallel of the load
Units for measuring voltage are known as?
volts

A device for measuring voltage, amperage and current.
What instrument used for measuring the voltage difference?
A VoltMeter
