A "transient network analyzer" was an analog model of a transmission system especially adapted to study high-frequency transient surges (such as those due to lightning or switching), instead of AC power frequency currents. Similarly to an AC network analyzer, they represented apparatus and lines with scaled inductances and resistances.
Electroshock weapons and tasers have a DC/AC inverter to generate several tens of thousands of V AC out of a small 9 V DC battery. First the 9 V DC is converted to 400–2000 V AC with a compact high frequency transformer, which is then rectified and temporarily stored in a high voltage capacitor until a pre-set threshold voltage is reached.
Friction will slowly bring any oscillation to a halt if there is no external force driving it. Likewise, the resistance in an RLC circuit will "damp" the oscillation, diminishing it with time if there is no driving AC power source in the circuit. The resonant frequency is defined as the frequency at which the impedance of the circuit is at a ...

The Jakarta–Bandung high-speed rail line (KCJB) has a track width of 1,435 mm (4 ft 8 1⁄2 in) and was initially powered by 25 kV AC overhead power. This line has been doubled since its construction for the first time. [20] During the trial process on May 18, 2023, the electric voltage was changed to 27.5 kV AC.
The Cockcroft–Walton (CW) generator, or multiplier, is an electric circuit that generates a high DC voltage from a low-voltage AC. [1] It was named after the British and Irish physicists John Douglas Cockcroft and Ernest Thomas Sinton Walton, who in 1932 used this circuit design to power their particle accelerator, performing the first accelerator-induced nuclear disintegration in history.

The CR400AF Fuxing (Chinese: 复兴号; pinyin: Fùxīng Hào) is a Chinese electric high-speed train developed by CRRC Changchun Railway Vehicles and manufactured by CRRC Qingdao Sifang.
In linear circuits, due to the superposition principle, the output of a circuit is equal to the sum of the output due to its DC sources alone, and the output from its AC sources alone. Therefore, the DC and AC response of a circuit is often analyzed independently, using separate DC and AC equivalent circuits which have the same response as the ...
