  2. Load regulation - Wikipedia

    en.wikipedia.org/wiki/Load_regulation

    The values of the resistors are selected such that R 1 gives the highest load resistance, R 1 ||R 2 gives the nominal load resistance and either R 1 ||R 2 ||R 3 or R 2 ||R 3 gives the lowest load resistance. A voltmeter is then connected in parallel to the resistors and the measured values of voltage for each load state can be used to calculate ...

  3. Voltage divider - Wikipedia

    en.wikipedia.org/wiki/Voltage_divider

    The output voltage of a voltage divider will vary according to the electric current it is supplying to its external electrical load. The effective source impedance coming from a divider of Z 1 and Z 2, as above, will be Z 1 in parallel with Z 2 (sometimes written Z 1 // Z 2), that is: (Z 1 Z 2) / (Z 1 + Z 2) = HZ 1.

  4. Output impedance - Wikipedia

    en.wikipedia.org/wiki/Output_impedance

    The output impedance is a measure of the source's propensity to drop in voltage when the load draws current, the source network being the portion of the network that transmits and the load network being the portion of the network that consumes. Because of this the output impedance is sometimes referred to as the source impedance or internal ...

  5. Impedance matching - Wikipedia

    en.wikipedia.org/wiki/Impedance_matching

    For example, in order to match an inductive load into a real impedance, a capacitor needs to be used. If the load impedance becomes capacitive, the matching element must be replaced by an inductor. In many cases, there is a need to use the same circuit to match a broad range of load impedance and thus simplify the circuit design.

  6. Voltage regulation - Wikipedia

    en.wikipedia.org/wiki/Voltage_regulation

    The Voltage Regulation formula could be visualized with the following: "Consider power being delivered to a load such that the voltage at the load is the load's rated voltage V Rated, if then the load disappears, the voltage at the point of the load will rise to V nl."

  7. Voltmeter - Wikipedia

    en.wikipedia.org/wiki/Voltmeter

    A voltmeter is an instrument used for measuring electric potential difference between two points in an electric circuit. It is connected in parallel . It usually has a high resistance so that it takes negligible current from the circuit.

  8. Electrical load - Wikipedia

    en.wikipedia.org/wiki/Electrical_load

    Load affects the performance of circuits with respect to output voltages or currents, such as in sensors, voltage sources, and amplifiers. Mains power outlets provide an easy example: they supply power at constant voltage, with electrical appliances connected to the power circuit collectively making up the load.

  9. Power-flow study - Wikipedia

    en.wikipedia.org/wiki/Power-flow_study

    In power engineering, the power-flow study, or load-flow study, is a numerical analysis of the flow of electric power in an interconnected system. A power-flow study usually uses simplified notations such as a one-line diagram and per-unit system, and focuses on various aspects of AC power parameters, such as Voltage, voltage angles, real power and reactive power.
