What is the current clamp?
The current terminal is a device used in electrical and electronic engineering, to measure electric current in conductive material. It consists partly of a pair of jaws that approaches the electric conductor to measure how the material flows through the electricity. Some types of jets are used to induct current into conductive material and also for measurement of this current. In this type of current terminal, the measured electrical current causes a change in the internal magnetic core of the device. This changing magnetic field moves with an iron shoulder blade, which in turn is determined on the indicator on the analog dial. Iron shoulder meter can be used to measure direct current (DC) and alternating current (AC).
The most common form of jet terminals often occurs in current transformers and serves a slightly different purpose than the type of iron blade. In them, it has a divided ring made of compounds with iron -out of this. This winding is a secondary part of the current transformer, while the conductive material forming PRan impassive part. The current terminal found in transformers is used to measure the current in the power grid and to monitor its operation. Transformers only work with alternate electricity, so this type of current clamp is therefore only useful when measuring AC
Another type of current clamp that measures AC and DC is the type of Hall effect. The name concerns the effect of the hall, which is an effect that has a magnetic field on the flow of electrons in the conductor. These current clamps are highly sensitive and are often used with computer voltmeters. They can be small enough to be hand and run on the nine volt battery. Hall clamping effect can also work with a wide range of AC frequency, sometimes up to 400 Hz.
In the field of biology, there is a highly specialized type of curprone terminal is used to measure the tension produced by one cell. Cell current clamps may record electrical activity outdoors and inside cellsy. Thus, a device that measures and records biological voltage is done through a microelectrode that is small enough to measure cellular electricity. The voltage they record are usually a minute of 0.0001 volts
