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.
What device is used to change the scale values of an AC ammeter?
A multimeter is used in which there is options for multirange measurement of Ac current or voltages and resistances and also DC voltages
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.
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

What type of accessory device can be used to measure AC with a VOM without opening the circuit?
A non-contact voltage tester can be used to measure AC voltage without physically making contact with the circuit. This type of tester can detect the presence of voltage by being held close to a wire or outlet. It is a safe and convenient way to measure voltage without the need for direct contact.
