The generic name given to any device that causes an electric current to flow continuously.
An electric device that fries when the current through it goes above a certain magnitude, thus creating an open circuit and preventing current from flowing.
Galvanic isolation of signal circuits means absence of DC coupling between them, “circuit ground” and other supply buses. Upon availability of galvanic isolation the potential of signal circuits against “circuit ground” can be significant but it can’t exceed the isolation voltage acceptable for the current interface.
A meter that indicates the magnitude of an electric current.
In electrical engineering, ground (grounding) or earth can refer to the reference point in an electrical circuit from which other voltages are measured, or a common return path for electric current, or a direct physical connection to the Earth.
The Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and a magnetic field perpendicular to the current.
A Hall probe contains an indium compound semiconductor crystal such as indium antimonide, mounted on an aluminum backing plate, and encapsulated in the probe head. The plane of the crystal is perpendicular to the probe handle. Connecting leads from the crystal are brought down through the handle to the circuit box.
The concept when dealing with alternating current that is equivalent to the concept of resistance when dealing with direct current.
Measuring instrument providing an output signal carrying information about the value of the quantity being measured. For example: ammeter, micrometer, thermometer, electronic balance.
In electromagnetism and electronics, inductance is that property of a conductor by which a change in current in the conductor "induces" (creates) a voltage (electromotive force) in both the conductor itself (self-inductance) and any nearby conductors (mutual inductance).
