Depends on the current. Put a resistor in-line with the current, then measure the
voltage across the resistor. V=RI. So, divide the measured voltage by resistor
value. Be careful with the size of the resistor, as Power dissipated in a resistor is
R*I^2 or V^2/2. So, a 1-Amp current into a 1 Ohm resistor will result in a 1Watt
power dissipated in the resistor. If it's too small, it'll burn.
Also, notice that if you do that, you haven't measured the current in the original circuit.
You've measured the current when an extra resistor is installed in the original circuit, and
that's different.

What Do Amps Measure?
You can measure the electrical current with an amp meter. Amperage measures the current flow.
What is the name of the meter that is used to measure current?
Electrical current is measured with an "ammeter". (The unit of current is "ampere". Measure it with an 'ampere-meter' ==> 'amp-meter' ==> 'ammeter'.)
What is tool for measuring the intensity of electric current?
An amp meter can measure the intensity of electric current.
Do amp meters measure power when device on circuit is turned off?
An amp meter measures current flow, not power. An amp meter measures instantaneous current either by being inserted in series with the wire being measured for current flow, or clamped onto a single current carrying wire and measuring current flow by induction. If the load is disconnected then no current will flow and the amp meter will read zero.CommentThe correct term is ammeter, not 'amp meter'.
Can you measure amp in the DC?
Yes but the meter has to go in series with the load. There is a new clamp on amp meter being introduced, that will measure larger DC amperages without opening the circuit.
What would be used if really low current was being measured?
To measure very low amperage a milli amp meter would be used or the milli amp scale on a multi meter.
Which energy meter is required for calculating DC?
Most volt/amp meters have a DC mode. You measure DC voltage by putting the two probes across the voltage source. You measure current by either putting the meter in series with the load or using a clamp on amp meter that measures current flow through induction.
How do you measure alternating current voltage and resistance?
You measure current by inserting an amp meter in series with the circuit or using a clamp-on meter to measure current by induction. You measure voltage with a volt meter across the supply. You measure resistance in ohms across the resistance. Luckily all these functions are in the same meter in most cases.
When a volumetr is connected in series with a battery what does it measure the ability to?
Measures the amperage of the current .Your battery is in series with your car amp meter .
What is used to measure the intensity of current flow in a circuit or branch in a circuit and is wired in series with the circuit being evaluated?
An Amp Meter
What is the instrument called that measures current?
The instrument used to measure electrical current is called an ammeter, which is actually a shortened form of 'amp meter'. The current is measured in amperes. In scientific labs, a much more sensitive instrument called a galvanometer is used to measure very small currents.
An amp meter measures?
Amperes of electrical current.
