  2. Load regulation - Wikipedia

    en.wikipedia.org/wiki/Load_regulation

    Load regulation is the capability to maintain a constant voltage (or current) level on the output channel of a power supply despite changes in the supply's load (such as a change in resistance value connected across the supply output).

  3. Charge amplifier - Wikipedia

    en.wikipedia.org/wiki/Charge_amplifier

    The charge signals at the input of a charge amplifier can be as low as some fC (FemtoCoulomb = 10 −15 C). A parasitic effect of common coaxial sensor cables is a charge shift when the cable is bent. Even slight cable motion may produce considerable charge signals which cannot be distinguished from the sensor signal.

    Continuous charge distribution. The volume charge density ρ is the amount of charge per unit volume (cube), surface charge density σ is amount per unit surface area (circle) with outward unit normal nĚ‚, d is the dipole moment between two point charges, the volume density of these is the polarization density P.

  5. Power (physics) - Wikipedia

    en.wikipedia.org/wiki/Power_(physics)

    The output power of a motor is the product of the torque that the motor generates and the angular velocity of its output shaft. Likewise, the power dissipated in an electrical element of a circuit is the product of the current flowing through the element and of the voltage across the element. [1] [2]

  6. Mathematics of three-phase electric power - Wikipedia

    Another example is the generation of higher-phase-order systems for large rectifier systems, to produce a smoother DC output and to reduce the harmonic currents in the supply. When three-phase is needed but only single-phase is readily available from the electricity supplier, a phase converter can be used to generate three-phase power from the ...

  7. SAE J1772 - Wikipedia

    en.wikipedia.org/wiki/SAE_J1772

    The SAE defines the ampacity value to be derived by a formula based on the 1 ms full cycle (of the 1 kHz signal) with the maximum continuous ampere rating being 0.6 A per 10 μs up to 850 μs (with the lowest (100 μs/10 μs) × 0.6 A = 6 A). Above 850 μs, the formula requires subtraction of 640 μs and multiplying the difference by 2.5.

  8. Power gain - Wikipedia

    en.wikipedia.org/wiki/Power_gain

    In electrical engineering, the power gain of an electrical network is the ratio of an output power to an input power. Unlike other signal gains , such as voltage and current gain, "power gain" may be ambiguous as the meaning of terms "input power" and "output power" is not always clear.

  9. Voltage regulation - Wikipedia

    en.wikipedia.org/wiki/Voltage_regulation

    In the voltage regulation formula, V no load is the voltage measured at the receiving end terminals when the receiving end is an open circuit. The entire short line model is an open circuit in this condition, and no current flows in an open circuit, so I = 0 A and the voltage drop across the line given by Ohm’s law V line drop = IZ line is 0 V.
