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

Why can't AC be measured by a Volt Ohm Meter?
Typical VOMs can measure both AC and DC.
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.
Can you measure AC current on a power cord?
Not very easily. A clamp on amp meter has to go around only one of the circuit conductors. If the clamp on meter is used around the power cord the two wires in the cord have a cancellation effect and the meter will read zero. If you can separate the load's wires that plug into the cord and clamp around that wire you will get a load amperage reading.
How do you calculate AC load from DC load?
Amp measurement in a dc circuit is commonly done by use of a clamp on amp meter. The meter has a loop on one end that opens up. The loop is clamped around a wire, and the meter shows the amperage.
What is the var meter?
A VAR Meter is used to measure Reactive Power in AC Circuits - Pure reactive components dissipate zero power, which makes sense in a DC circuit, as a capacitor passes no DC current and an inductor displaces no voltage. Yet, in an AC circuit, the reactive components "seem" to dissipate power, as current passes through the capacitor and the inductor sees a voltage drop. This counterfeit power is called "reactive power" and is measured not in Watts, but in VARs (Volt-Amps-Reactive). Its mathematical formula symbol is "Q".

How do electricians check current flow in a circuit?
For AC circuits, amperage is checked with a clamp on amp meter. There is now in the market place a clamp on amp meter that will work on both AC and DC circuits.
What is the result of 230VAC divided by 30 ohms?
7.6667
Why can't AC be measured by a Volt Ohm Meter?
Typical VOMs can measure both AC and DC.
How do you calculate ampere given 250v AC 60W?
Divide the watts by the voltage to get current (amps). 60W / 250V = about 1/4 Amp.
What is the difference between Kilovolt Ampere and Kilowatt?
A kilowatt is an unit of true power in an AC circuit -as measured by a wattmeter. A kilovolt ampere is an unit of apparent power in an AC circuit, which is the product of the voltage across a load by the current through it. The relationship between the two is: kilowatt = (kilovolt ampere) x (power factor of load)
Why current is measured in sereis?
It actually never is measured in series on a meter. AC can be measured by a meter clamp where is the coupling of flux can be measured. A normal meter will read the small voltage drop cause by current flowing through a series resistance. this small voltage drop will indicate current flow the magnitude is a function of scaling.
What is amp rating of 1 ton split AC?
1 ton ac amp
How do you work out ampere hour?
An ampere-hour is one ampere for one hour.A ampere is one coulomb per second, so an ampere-hour is a transfer of charge of 3600 coulombs.See the discussion page.
How many kilowats are in 1 amp?
Watts (or kilowatts) and amperes are used to measure different things. Watts is a unit of power; ampere is a unit of current. The relationship (for direct current) is: watt = ampere x volt For AC, the relationship is a bit more complicated: watt = ampere x volt x power factor However, the power factor is often close to one.
You want to connect car sub woofer amplifier to AC 220 volts by using a step down transformer What should be the output ampere for the transformer so that you can use the car sub whoofer amp with AC?
About 1A To 1.5A (or 2A) i tested it one month ago.
What unit is current measure in?
Electrical currents are measured in a unit called amperes, which are abbreviated as "amps." There are two different designations that measure currents: direct currents (DC) and alternating currents (AC). Amperes are coulombs per second. Amperes are electrical current units that are part of the meter-kilogram-second system. A flow of one coulomb per second is equivalent to one single ampere.
How many ampere in 85 watts fan motor?
An 85 watt fan motor, working on ac, would probably have a power factor of about 0.75 so would draw 113 VA. The estimated current would be 1 amp on a 120 v supply or ½ amp on a 240 vsupply.
