2. Current clamp - Wikipedia

   en.wikipedia.org/wiki/Current_clamp

   Clamp meter. 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 ...

3. Electrophysiology - Wikipedia

   en.wikipedia.org/wiki/Electrophysiology

   The current clamp technique records the membrane potential by injecting current into a cell through the recording electrode. Unlike in the voltage clamp mode, where the membrane potential is held at a level determined by the experimenter, in "current clamp" mode the membrane potential is free to vary, and the amplifier records whatever voltage ...

4. Current sensing - Wikipedia

   en.wikipedia.org/wiki/Current_sensing

   The measurement of the electric current can be classified depending upon the underlying fundamental physical principles such as, Faraday's Law of Induction; Magnetic field sensors; Faraday effect; Transformer or current clamp meter, (suitable for AC current only). Fluxgate sensor, (suitable for AC or DC current).

5. Four-terminal sensing - Wikipedia

   en.wikipedia.org/wiki/Four-terminal_sensing

   Four-point measurement of resistance between voltage sense connections 2 and 3. Current is supplied via force connections 1 and 4. In electrical engineering, four-terminal sensing (4T sensing), 4-wire sensing, or 4-point probes method is an electrical impedance measuring technique that uses separate pairs of current-carrying and voltage-sensing electrodes to make more accurate measurements ...

   Measures current Capacitance meter: Measures the capacitance component Current clamp: Measures current without physical connection Curve tracer: Applies swept signals to a device and allows display of the response Cos Phi Meter: Measures the power factor Distortionmeter: Measures the distortion added to a circuit Electricity meter

7. Shunt (electrical) - Wikipedia

   en.wikipedia.org/wiki/Shunt_(electrical)

   A shunt is a device that is designed to provide a low-resistance path for an electrical current in a circuit. It is typically used to divert current away from a system or component in order to prevent overcurrent. Electrical shunts are commonly used in a variety of applications including power distribution systems, electrical measurement ...
