How do you calculate the ac amps when you have the DC volts DC amps and the ac volts?

the answer is dc volts are rectified from ac volts and the amperage will be the same unless you account for the slight drop from the rectifier. dc volts from a battery have no relationship to ac volts. you can derive ac volts from a dc source using an inverter.

Can amps go up if volts goes down in AC?
No, Ohms Law applies equally well in ac as in dc.
What are the function of multimeter?
They allow the user to test: Volts (AC and DC), Amps, Ohms and basic continuity.
Convert 18 VDC to AC amps?
Amps is amps be it DC or AC.
What does a Simpson Meter do?
It measures potential difference, current, and resistance (volts, amps, and ohms), in several AC and DC ranges.
How many dc volts does it take to make 1 horsepower?
Volts don't make power. Watts do. Watts = (volts) x (amps) 1 horsepower = 746 watts (Doesn't matter if the source is AC, DC, or a combination of both.)
If a battery has 100 amp hours at 12 volts dc how many amp hours will it have with a 120 volt ac inverter connected?
12 Amps x 12 volts = 1200 watts 1200 watts / by 120 volts = 10 amps at 120 volts Answer is 10 amp hours
Why AC is dangerous as compare to DC for same amount of voltage?
The danger is in the voltage, not if it is ac or dc. For instance, 12v dc or 12v ac makes no difference in body contact. Neither will shock you. Usually 24 volts will not shock either. When you get to 48 volts or greater, then you have a chance of shock. 100 volts Ac or Dc shocks basically the same. 120 volts AC is actually 144 volts peak to peak, so 120 volts AC is slightly worse than 120 volts DC. Amperage is actually what kills. A "Taser" voltage can be as high as 50,000 V but the amps are so slow that it doesn't do permanent damage. Commonly people are shocked accidentally by a spark plug wire on a car or a lawnmower with no lasting or ill effects. This voltage can range from 15,000 volts to more than 50,000. These systems have very low amperage.
What is an ac voltmeter?
A: It is a regular DC voltmeter but the AC is rectified and the DC component is measured and displayed as AC VOLTS.
How do you calculate hp from amps?
1 HP is 746 watts in principle. The power is in watts, and the power is the volts times the amps. For an AC motor the power is the volts times the amps times the power factor times a factor that depends on the power-conversion efficiency of the motor.
How do you calculate amperage when given the values of watts and volts?
With an instrument called a multimeter. The single meter incorporates within it a volt meter, an ohm meter and an amp meter. For higher amperages a clamp on amp meter is recommended as the circuit does not have to be opened to take a reading.
How many ac amps is a 1500 watts?
Watts are amps x volts, so w/o the volts the question can't be answered. At 100 volts it'd be 15 amps.
The working voltage of a capacaitor is rated in ac or dc volts?
DC
