2. 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 ...

3. LCR meter - Wikipedia

   en.wikipedia.org/wiki/LCR_meter

   An LCR meter is a type of electronic test equipment used to measure the inductance (L), capacitance (C), and resistance (R) of an electronic component. [1] In the simpler versions of this instrument the impedance was measured internally and converted for display to the corresponding capacitance or inductance value.

4. Contact resistance - Wikipedia

   en.wikipedia.org/wiki/Contact_resistance

   The direct methods able to measure potential drop on the injection electrode directly are the Kelvin probe force microscopy (KFM) [5] and the electric-field induced second harmonic generation. [ 6 ] In the semiconductor industry, Cross-Bridge Kelvin Resistor(CBKR) structures are the mostly used test structures to characterize metal ...

5. Battery tester - Wikipedia

   en.wikipedia.org/wiki/Battery_tester

   Battery tester. A battery tester is an electronic device intended for testing the state of an electric battery, going from a simple device for testing the charge actually present in the cells and/or its voltage output, to a more comprehensive testing of the battery's condition, namely its capacity for accumulating charge and any possible flaws affecting the battery's performance and security.

6. This electric car battery takes less than 5 minutes to charge

   Nyobolt is currently in talks to sell its batteries to eight electric car manufacturers. At 35 kWh, the battery is much smaller than the 85 kWh in a more typical American electric vehicle (EV ...

7. Kelvin bridge - Wikipedia

   en.wikipedia.org/wiki/Kelvin_bridge

   The operation of the Kelvin bridge is very similar to the Wheatstone bridge, but uses two additional resistors. Resistors R 1 and R 2 are connected to the outside potential terminals of the four terminal known or standard resistor R s and the unknown resistor R x (identified as P 1 and P′ 1 in the diagram).
