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.


Can DC ampere be measured with AC amp meter?

No. The ammeter must be designed to measure DC. Some clamp-on ammeters are designed to measure both AC and DC.


Can you measure ac mains voltage with dc voltmeter or high dc voltage with ac meter?

You cant.


What has the author Jae-Won George Hwang written?

Jae-Won George Hwang has written: 'Control of AC-DC-AC converters with minimized DC link capacitance under grid harmonic distortion'


How many things can a multi meter measure?

Resistance Voltage (both AC and DC) Current (both AC and DC)


What value of voltage measure by DMM Vrms or Dc voltage?

Many can measure both - Vrms (AC) or DC voltage.


What are the three main function of the multimeter?

A typical multimeter can measure: * AC & DC voltage (volt) * AC & DC current (amp) * resistance (ohm)


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


Why can't AC be measured by a Volt Ohm Meter?

Typical VOMs can measure both AC and DC.


Why the common mode signal should be rejected in differential amplifier?

because of the coupling between the two transister and absence of capacitance it can amplify both dc and ac


If ad is 10 units and ab is 8 units what is the measure of dc?

Given that AB = 8 units and AD = 10 units, we can use the ratios of corresponding sides in similar triangles to find the measure of DC. Since triangle ADC is similar to triangle ABC, the ratio of DC to AB is equal to the ratio of AD to AC. Thus, DC/8 = 10/AC. Solving for DC, DC = 8 * 10 / AC.


Why capacitance is not used in DC circuits?

as it acts ideally as open circuit for dc
