A current measuring clamp is a device that can measure direct and alternating current in current-carrying conductors. By means of its ring-shaped measuring terminal, which looks like a pliers head, it can detect the magnetic flux density around the conductor and consequently also the strength of its current.
In electrical and electronic engineering, a current clamp, also known as current probe, is an electrical device with jaws which open to allow clamping around an electrical conductor. This allows measurement of the current in a conductor without the need to make physical contact with it, or to disconnect it for insertion through the probe.
The working principle of a current clamp meter revolves around the concepts of electromagnetic induction. It encapsulates Faraday’s law, which states that a change in the magnetic field within a loop of wire induces an electromotive force (EMF) in the wire.
The clamp on ammeter is a portable instrument designed to give a quick measurement of current flow, without breaking the circuit. There are no connections to be made; it simply clips over the conductor/cable.
The ideal voltage-clamp circuit simply consists of a battery, a switch, a wire, the cell and an ammeter. In an experiment, one controls the membrane voltage and measures the transmembrane current required to maintain that voltage. When the switch closes, the membrane potential steps instantly to the battery voltage.
It consists of a split core current transformer with a single conductor as shown; the core can be opened temporarily so as to enclose the current carrying conductor without the need for breaking the circuit to connect the ammeter. Clamp-on ammeter operates on the principle of induction.

As a measurement principle, clamp meters detect the magnetic field emitted by current flowing in a wire in order to measure the current value. Unlike instruments like multimeters, this design has the advantage of being able to measure current without requiring that the circuit under measurement be cut.
Ohm''s Law. Ohm''s Law, a fundamental principle in electrical engineering, establishes a foundational relationship between resistance, voltage, and current in a circuit.Named after the German physicist Georg Ohm, the law states that the current passing through a conductor between two points is directly proportional to the voltage across the two …

Current clamps operate based on two key principles: the magnetic induction for AC measurements, and the Hall effect for DC measurements. The clamp, when closed around a conductor, forms a magnetic core and measures the magnetic field around the conductor.
The clamp measures the current and other circuitry the voltage; the true power is the product of the instantaneous voltage and current integrated over a cycle. Comprehensive meters designed to measure many parameters of electrical energy ( power factor, distortion, instantaneous power as a function of time, phase relationships, etc.), use this principle.
How does a current clamp measure electric current? Current clamps work by measuring the magnetic field generated by the electric current flowing through a wire.
