2. Current sensing - Wikipedia

   en.wikipedia.org/wiki/Current_sensing

   The design of the saturable inductor current sensor is similar to that of a closed-loop Hall-effect current sensor; the only difference is that this method uses the saturable inductor instead of the Hall-effect sensor in the air gap. Saturable inductor current sensor is based on the detection of an inductance change. The saturable inductor is ...

3. Current sense amplifier - Wikipedia

   en.wikipedia.org/wiki/Current_sense_amplifier

   They utilize a "current-sense resistor" to convert the load current in the power rail to a small voltage, which is then amplified by the current-sense amplifiers. The currents in the power rail can be in the range of 1 A to 20 A, requiring the current-sense resistor to be a resistor typically in the range of 1 to 100 mΩ.

4. Wiring diagram - Wikipedia

   en.wikipedia.org/wiki/Wiring_diagram

   An automotive wiring diagram, showing useful information such as crimp connection locations and wire colors. These details may not be so easily found on a more schematic drawing. A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the ...

5. 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 ...

6. Hall effect sensor - Wikipedia

   en.wikipedia.org/wiki/Hall_effect_sensor

   Hall effect current sensor with internal integrated circuit amplifier. 8 mm opening. Zero current output voltage is midway between the supply voltages that maintain a 4 to 8-volt differential. The non-zero current response is proportional to the voltage supplied and is linear to 60 amperes for this particular (25 A) device.

7. 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 ...

8. Glossary of electrical and electronics engineering - Wikipedia

   en.wikipedia.org/wiki/Glossary_of_electrical_and...

   The current carrying capacity of a conductor, in the context of electric power wiring. ampere The SI unit of electrical current. Ampère's circuital law The mathematical relation between the integral of the magnetic field over some closed curve to the current passing through the region bound by the curve. Ampère's force law

9. Hall effect - Wikipedia

   en.wikipedia.org/wiki/Hall_effect

   The conventional "hole" current is in the negative direction of the electron current and the negative of the electrical charge which gives I x = ntw(−v x)(−e) where n is charge carrier density, tw is the cross-sectional area, and −e is the charge of each electron.
