A continuity test checks to ensure that there is no break in the conductors. An insulation test checks to ensure that the insulation is sound.

Why high voltage transformers have graded insulation?
It is to decrease the amt of insullation materials used. It can be used only for star connection.Answer'Graded insulation' is all about controlling the shape of the electric field within the insulator to prevent breakdown due to local peaks in potential difference across that insulation.
Is coulomb a unit for a resistance?
No. It is the unit for electric charge. The unit for resistance is the ohm.
8 If the resistance of an electric circuit is 12 ohms and the voltage in the circuit is 60 V the current flowing through the circuit is?
There is a simple equation relating voltage (properly potential difference), current and resistance: V=IR Where V=potential difference, I=current and R=resistance So to answer: I=60/12 I=5
Is the increase in voltage causes a greater electric resistance in a circuit?
No, the resistance in a circuit does not change when voltage changes. Resistance is an inherent property of the circuit.
What are ohms used for?
Ohms are used to measure electric resistance.
What has the author G F Tagg written?
G. F. Tagg has written: 'Earth resistances' 'The practical measurement of insulation resistance' -- subject(s): Electric insulators and insulation, Electric resistance, Testing
What is the difference between a resistance and a capacitor?
resistance refers to the resistance of flow of electric current wile a capacitor is an electric device that stores energy.
Why multimeter cannot used for measurement of insulation resistance?
Because ordinary ohmmeters are calibrated to measure a range of resistance values that are significantly lower than the resistance of insulation. It should also be realised that we usually test insulation resistance while subjecting the insulation to a high electric field, which a normal ohmmeter is incapable of producing.
In an electric circuit resistance is?
Resistance is the opposition to the flow of electric current through a conductor. It is defined as the ratio of the potential difference (volts) between the ends of the conductor to the magnitude of the current (amps) through the conductor.
What is continuity test?
a continuity test is the checking of an electric circuit to see if current flows. That it is in fact a complete circuit.
What is a continuity test?
a continuity test is the checking of an electric circuit to see if current flows. That it is in fact a complete circuit.
What is the difference of efw and erw?
EFW: Electric Fusion Welding is a more general term which includes Electric resistance welding (ERW) and other types of welding such as Arc welding.

What is the use of continuity on electrical cables?
Without continuity they would not conduct electricity so as electric cables they would be a non-starter.
What is the difference between electric and manual treadmills?
A manual treadmill takes no electricity and uses resistance. The person running on it makes it work. Electric moves at set speeds by motor.
Does an electric motor have different resistance than an electric heater?
Yes it would be unlikely an electric motor coincidentally exactly matched the resistance of an electric heater.
What is the SI unit for an electric resistance?
The unit for resistance is the Ohm.
