clamp is an electrical device having two jaws which open to allow clamping around an electrical conductor. This allows properties of the electric current in the conductor to be measured, without having to make physical contact with it, or to disconnect it for insertion through the probe.

What is a tong amp meter?
A type of current transformer used as a metering device. You clamp the tong around a wire and it will tell you how many amps are flowing though it.
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 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 size wire for 2 100 amp meters?
1awg
What is difference between 5 amp and 15 amp plug points?
Current carrying capacity is different.
How do you find the current in a wire?
Open the circuit and put an amp meter in series. There are clamp on current meters. You don't need to break the circuit.
How do electricians check current flow in a circuit?
For AC circuits, amperage is checked with a clamp on amp meter. There is now in the market place a clamp on amp meter that will work on both AC and DC circuits.
What Do Amps Measure?
You can measure the electrical current with an amp meter. Amperage measures the current flow.
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.
Why neutral wire does not carry current in closed ac circuit?
The neutral wire does carry current in a closed AC circuit. Clamp a clamp on amp meter around the neutral wire directly after the circuit load and it will read the same current as is on the "hot" wire.
How can you tell that there is a current in a wire?
A clamp on amp meter is used for this purpose. When amperage is present in a wire there will be a magnetic field generated around the wire. The clamp on amp meter measures this magnetic field and converts it to an amperage value that is read on the screen of the amp meter. No current flow, no magnetic field, no reading. A dangerous and non recommended way to check current flow is to open the circuit when the load is connected and operating. There will be a small arc that jumps across the gap when the circuit is opened. This is current flowing in the circuit.
What is the sign for amp on a volt clamp meter?
A
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'.
How do I use a clamp on amp meter?
Answer 1When electrical current flows through a wire [or any conductor[, it creates an electromagnetic field which the clamp on Amp meter is disigned to detect and quantify. The meter loop is hinged and movable in order to open the loop to allow the loop to be placed "around" a single conductor. It is important that the loop be placed around only one conductor as if there is more than one wire conducting, then the fields from multiple wires will interfere with the meters ability to operate.The meter will have a switch [usually rotary] to change scales, and unless you know the approximate current flowing through the circuit, you should first set the meter to the highest current scale setting, and then switch to lower current scales until the proper one is found.
What is a tong amp meter?
A type of current transformer used as a metering device. You clamp the tong around a wire and it will tell you how many amps are flowing though it.
Amp meters how do they work?
A current probe, or current clamp, is a device having jaws which allows clamping around an electrical conductor, measuring the current without touching the conducting material. This measurements comes from a second current generated by the magnetic field created from the first electrical current.
How do you multiply current transformer output?
There are many ways but never can you multiply the power. <<>> A current transformer is specifically designed, by amp turns, to only output 5 amps. Meters that are connected to CT's have a full range deflection (scale) of 5 amps. To do what you are asking seems pointless as there are no meters with 10 amp full scale deflection.
