Why ac megger not use in cable meggering?
Because the cable has capacitance, and an AC source would not be able to distinguish between capacitance and leakage.
Why is AC meggering not used?
You do not use AC to megger a device, because the purpose of meggering is to measure the insulation resistance of the device. You use DC to do that. If you used AC, you would be unable to differentiate between insulation leakage and capacitance.
What is the use of a regulator?
ac supply converted with dc supply
What is the use of regulator?
ac supply converted with dc supply
How can a radio use both DC and AC?
Radios use DC power supplies to operate. If a radio is powered from a mains AC supply, a power supply circuit will convert the AC supply to DC. Therefore, a radio may have both a DC and an AC power input but ultimately, the internal circuitry will always use DC.
What cable would you use in a camper van to add a bathroom extractor fan?
use a cable that is specified on the fan AC OR DC
Why does Jim use dc supply in oscillator circuits?
Jim use dc supply in oscillator circuits to and ac out put.
Can AC cable use for DC motor?
Yes, what matters is that the cable can take the correct voltage, and is thick enough to carry the required current, but ac or dc makes no difference.
Megger testing is done with DC or AC votage?
Earth testing results should be related to the voltage source, i.e., AC in most situations. AC reacts to resistive and reactive loads, DC to resistive loads only. Not all earth testers, however, use AC.
Why less loss occurs when you use DC supply than AC supply?
There are less loss occurs when we use DC supply than AC supply, because the frequency is zero in DC, so no Inductance & Capacitance exists.And there is no skin effect in the DC systems, so there is low resistance as compared to AC systems.Rac = 1.25*Rdcfrom Arun Kumar SRR
Can an amplifier can be operated on ac supply?
Yes, an amplifier can be operated on ac supply.
What supply should be given for making electro magnets... ac or dc?
For a simple electro-magnet use a DC supply.
