How do you measure the current through a circuit without intercepting the supply?

Add an ammeter in parralel with the circuit. An ammeter in parallel with a circuit to be measured will not measure any current. In fact, placing an ammeter in parallel will cause a short. The ammeter must be placed in series with the circuit to be measured. It should be noted that this technique only allows for small magnitudes of current to be measured. One should not try to measure more than 10 amps using this method. However, this is not the goal of the question asked. I am not 100% sure what "intercepting the supply" means but I think the person asking the question means without breaking the circuit? In this case one could use a clamp on ammeter. There are several varieties that can measure low currents and there are those that can measure 100s of amps.

What is ammeter used for?
An ammeter measures the electrical current in something. A digital one is calibrated to display through the shunt and convert information from the analog model.
The measure of how difficult it is for electrons to flow through a circuit is called what?
The measure of how difficult it is for electrons to flow through a circuit is called resistance.Another AnswerResistance is not a measure of 'how difficult' it is for electrons to flow through a circuit. It is more accurate to describe it as a measure of whether a material can supportcurrent flow.For example, it's incorrect to say that an insulator 'blocks' current flow. It's more accurate to say that it has an insufficient amount of charge carriers to support an electric current.
What kind of circuit allows a current to flow through?
Any complete circuit. ==== An electrical circuit.
Why is voltmeter is connected in parallel and ammeter in series?
Because its function is to measure the current, i.e. the amount of electrical flow in the circuit, and this require that the current flows through the ammeter A good ammeter has very low series resistance, so connecting it in series will not affect your circuit. Be careful when using an ammeter , because of its very low resistance , it can cause a short circuit if you use it by mistake to measure "voltage", so avoid connecting it in Parallel.
Which property makes it difficult for current to pass through?
Resistance in the circuit makes it difficult for current to pass through.
Do You measure current across a circuit?
A current flows through, not across, a circuit. And, yes, you can measure it using an ammeter.
Why does not it matter where you measure the current in a simple circuit?
The current measured at any point in a simple circuit will be the same because current is the measure of electron flow through a circuit. The current flowing through any branch of any circuit (or an entire simple circuit) will always be the same at any point.
What do ammeters do?
Ammeters measure the current flowing through a circuit
What measures the volume of electrons through a circuit?
Current measures the flow of electrons through a circuit and voltage basically measure the amount of available electrons.
What are the function of ammeter?
The purpose of an ammeter is to sense and display the magnitude of the current flowing through it. When connected in series with a branch of an electrical circuit, the meter displays the magnitude (and direction) of the current in that path ... which you can't otherwise tell just by looking at the circuit.
How current transformer measure current?
A current transformer doesn't 'measure current'. It merely reduces a large current flowing through its primary to a smaller current which can be read by an ammeter connected to its secondary. At the same time, it electrically isolates the secondary circuit from the primary circuit, which is essential if the primary circuit is part of a high-voltage system.
What is ammeter used for?
An ammeter measures the electrical current in something. A digital one is calibrated to display through the shunt and convert information from the analog model.
Where is the best place to put an ammeter in the circuit to measure the current going through the light bulb?
Since (by Kirchoff's current law) the current in a series circuit is the same at every point in the series circuit, it does not matter where you place the ammeter.
What does A with a ring round it stand for in a circuit?
It stands for an ammeter - a meter that measures current (in Amperes - hence the 'A'). It is usually connected in series within the circuit, to measure the current as it passes through it.

Does an ammeter measure current?
An ammeter measures the amount of current flowing through an electrical circuit. It measures amperage.
What electrical quantity is the same throughout a series circuit?
In any series circuit, there is one and only one path for current flow. All the current flowing in the circuit will flow through all of the devices in that circuit. A break at any point in the circuit will cause current flow to cease. Lastly, it is current that is the same at any point in the circuit where we'd care to measure it.
