It depends. If it's an inductive ammeter (the kind that clamps around a wire), it won't work at all. If it is the type of ammeter that is actually placed in the circuit, it will work but it won't be accurate.

Actually, modern 'clamp on' ammeters WILL measure d.c. currents. It uses the Hall Effect to measure the current.

Does an ammeter measure current?
An ammeter measures the amount of current flowing through an electrical circuit. It measures amperage.
When measuring with an ammeter the ammeter must be connected in?
When measuring a load current, an ammeter is connected in series with the load. The exception is for a clamp on style AC ammeter, which is clamped around one of the conductors, making its measurements as a transformer.
Why shouldn't ammeter be connected in parallel?
A: An ammeter actually is a voltmeter measuring the voltage drop across a very small shunt resistance. They can measure AC or DC, make sure the meter is rated for the anticipated current, and always connect in series.
How is an ammeter converted to a voltmeter?
The ammeter is used in series, because you want to measure the current through a circuit. The voltmeter is used in parallel, because you want to measure the voltage across a circuit. If you were to place the voltmeter in series, no current would flow because of the relatively high impedance of the voltmeter. If you were to place the ammeter in parallel, you would create a short-circuit, due to the relatively low impedance of the ammeter.
How do you measure voltage?
Voltage can be measured using the difference between the potentiel between two ends of wire or by using a volt-meter. You can easily measure volt by volt or multimeter but remember voltage always measure across the components but in parallel
4Ub.Which instruments can measure AC current in electric circuit?
ammeter
Does an ammeter measure current?
An ammeter measures the amount of current flowing through an electrical circuit. It measures amperage.
How do you measure alternative current using ac ammeter?
I think you mean 'alternating' current ('alternative' means choice). The ammeter must be inserted in series with the load, just as with direct current.
How do you increase current capacity of an ammeter?
In measuring high AC currents a current transformer with a suitable rating say 100/5 or 1000/5 are used. The secondary current is usually 5 amps when the fulload current of 100 or 1000 as the case may be is flowing in the mains. It is the univerasl practice to use CT's for measurement of AC currents. In DC circuits the transformer method will not work, so to increase the current that you can measure you can allow a known amount of current to bypass the ammeter and recalibrate the ammeter. In other words, put a shunt in parallel with the ammeter.
What kind of ac ammeter does most electricians use?
I use a Fluke ammeter.
What would you do to measure the current in a resistor?
Since the current in a resistor is the same as the current in the leads/wires on either side of the resister, I might use a clamp meter such as an Amprobe to measure current, if the current was alternating (AC). Otherwise, I would have to break one of the leads and insert an ammeter or a multimeter with an amp setting into the circuit. Afterwards the broken connection would have to be repaired.
What type of accessory device can be used to measure AC with a VOM without opening the circuit?
Electricians use a clamp or clamp-on ammeter to measure current. The handles are squeezed together and the "jaws" open up. The clamp is then slipped over the conductor and the handles are released. The "jaws" close around the conductor and the meter is then in a position to measure current in that conductor. When current flows in a conductor, the current generates a magnetic field around the conductor. And the clamp-on ammeter can "feel" the current and measure it, thus permitting an investigator to know how much current is flowing in that conductor. The clamp-on ammeter is a stand-alone meter, but can sometimes be the kind that is plugged into a digital multimeter (DMM). A link to the Wikipedia article on the clamp ammeter is provided.
Heat anticipater setting?
Usually refers to the current (AC AMPS) that flows through the thermostat. Use an AC ammeter to measure the current across the (heat) terminals. Usually .1 - .9 AC amps. It is used to fool the furnace to shut off a little early so that the residual heat in the furnace won't increase the room temperature beyond the temperatur setting.
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.
Ammeter is a device used for measuring?
Measures current, both AC or DC, usually in Amps.
What is the difference between ac ammeter and dc ammeter?
dc ammeter has three connecting pins while ac has four
When measuring with an ammeter the ammeter must be connected in?
When measuring a load current, an ammeter is connected in series with the load. The exception is for a clamp on style AC ammeter, which is clamped around one of the conductors, making its measurements as a transformer.
