    Tesla coil, 0.76 meters (2 ft 6 in) high, at 200 kV and 270 kV peak [4] 2.1 A High power LED current (peak 2.7 A) [5] 5 A One typical 12 V motor vehicle headlight (typically 60 W) 9 A 230 V AC, toaster, kettle (2 kW) 10 1: 10 or 20 A 230 V AC, Europe common domestic circuit breaker rating 15 or 20 A

  3. Inrush current - Wikipedia

    en.wikipedia.org/wiki/Inrush_current

    Inrush current, input surge current, or switch-on surge is the maximal instantaneous input current drawn by an electrical device when first turned on. Alternating-current electric motors and transformers may draw several times their normal full-load current when first energized, for a few cycles of the input waveform.

  4. Peak demand - Wikipedia

    en.wikipedia.org/wiki/Peak_demand

    Peak demand is typically characterized as annual, daily or seasonal and has the unit of power. [1] Peak demand, peak load or on-peak are terms used in energy demand management describing a period in which electrical power is expected to be provided for a sustained period at a significantly higher than average supply level. Peak demand ...

  5. Load management - Wikipedia

    en.wikipedia.org/wiki/Load_management

    Capacity factor is a measure of the output of a power plant compared to the maximum output it could produce. Capacity factor is often defined as the ratio of average load to capacity or the ratio of average load to peak load in a period of time. A higher load factor is advantageous because a power plant may be less efficient at low load factors ...

  6. Audio power - Wikipedia

    en.wikipedia.org/wiki/Audio_power

    This determines the peak momentary output power for a given load resistance. [1] [2] Current: The amp's output devices (transistors or tubes) have a current limit, above which they are damaged. This determines the minimum load resistance that the amp can drive at its maximum voltage. [3]

  7. Power amplifier classes - Wikipedia

    en.wikipedia.org/wiki/Power_amplifier_classes

    Each conducts for one half (180°) of the signal cycle, and the device currents are combined so that the load current is continuous. [12] At radio frequency, if the coupling to the load is via a tuned circuit, a single device operating in class B can be used because the stored energy in the tuned circuit supplies the "missing" half of the ...

  8. Pre-charge - Wikipedia

    en.wikipedia.org/wiki/Pre-charge

    A high-voltage system with a large capacitive load can be exposed to high electric current during initial turn-on. This current, if not limited, can cause considerable stress or damage to the system components. In some applications, the occasion to activate the system is a rare occurrence, such as in commercial utility power distribution.

  9. Load factor (electrical) - Wikipedia

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

    In electrical engineering the load factor is defined as the average load divided by the peak load in a specified time period. [1] It is a measure of the utilization rate, or efficiency of electrical energy usage; a high load factor indicates that load is using the electric system more efficiently, whereas consumers or generators that underutilize the electric distribution will have a low load ...
