There are two ways. With small circuit currents, connect an amp meter in series with the circuit that you want to measure. The meter actually becomes part of the circuit. The second way is with a clamp on amp meter. On AC circuits it acts like a transformer. The magnetic field that is created around a wire, when the current is flowing, cuts the wire coils in the clamp on meter and gives a calibrated readout on an analog or digital readout in the handle of the meter.

∙ 11y agoThe only reliable method of obtaining reasonably accurate voltage and current
measurements is to use meters designed for the purpose and maintained in
reasonably good condition. For the best accuracy, the test equipment ... even
the lowliest multimeter ... is calibrated periodically against traceable standards.

Which instrument do you use to measure the flow of current in a circuit?
To measure current you will need an ammeter.
Which component is used to measure the current in a circuit?
an ampmeter. Most DVM's have them, or you can use a clamp on style.
Can you use electronic circuit as a load?
If you are just using the load to pull a small amount of current, then yes a electronic circuit can be used for that. If you want a resistive load to measure voltage drop or something similar, then no an electronic circuit will usually not work for that.
Can you use ac ammeter to measure dc current?
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.CommentActually, modern 'clamp on' ammeters WILL measure d.c. currents. It uses the Hall Effect to measure the current.
Why should you never measure resistance in a circuit carrying a current?
Ideally true, but seldom so. The vast majority of resistance meters use current to measure resistance and just use V=IR to give R - the resistor is in a circuit carrying current. The only method that does not have a current through the resistance, it actually relies on the fact, is a Wheatstone bridge. The most important reason for not having a current is that you will be using a current in most cases, to meaure the resistance. Current from another source will screw the reading. Also, with a current flowing, you are not measuring resistance - you are measuring impedance - a combination of inductance and resistance.
What do you use to measure a a current circuit?
Ammeter

What is the use of ammeter?
To measure the current in an electrical circuit.

When measuring current always place any type of meter in series with the circuit--is this true?
No. While it is true that one can measure current at any point in a circuit by breaking the circuit at that point and inserting the meter, not any meter will do it. One must use an ammeter to measure current.
Which component is used to measure the current in a circuit?
an ampmeter. Most DVM's have them, or you can use a clamp on style.
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 do you measure with electric current?
I presume you mean what do you measure electric current with. You would use an ammeter.
Where can one purchase a current probe?
One can purchase a current probe from the tek website. One can also purchase the current probe from Amazon. One can use the current probe to measure circuit.
What code would you use to declare a variable that can store the current in a circuit?
double variable_list;
Why don't we use an ammeter in series?
You do use an ammeter in series. It has a very low resistance, which according to ohms law, makes it ideal for measuring current. You do not use a volt meter in series, as it has a very HIGH resistance and would not allow current to flow. You measure the voltage across a component (or components), and current through a circuit.
How is current measured in a series circuit?
Current is measured in a series circuit by the use of a multimeter. First, the power source must be attached to the circuit board. The board is attached to the multimeter, then that is attached back to the power source.AnswerCurrent is measured either with an ammeter, or with a multimeter set to measure current. The instrument must be connected in series with the other components in the circuit.
