Dieseling or engine run-on is a condition that can occur in spark-plug-ignited, gasoline-powered internal combustion engines, whereby the engine keeps running for a short period after being turned off, drawing fuel through the carburetor, into the engine and igniting it without a spark.
The sparks generated by static electricity can generate interference. Many systems where radio frequency interface is caused by sparking can be modeled as the following circuit. The source of energy charges C1 via a resistance, and when the spark gap breaks down, the electricity passes through L and excites the resonant LC circuit.
Thus, the lamp can be "turned on" or "turned off" even though in reality the bulb is always on. In 2015, the KosherSwitch wall switch was introduced amid controversy, [72] as a means of controlling electricity on-demand in a manner that is permissible according to several Orthodox authorities.

Timers can be used to turn off standby power to devices that are unused on a regular schedule. Switches that turn the power off when the connected device goes into standby, [30] or that turn other outlets on or off when a device is turned on or off are also available. Switches can be activated by sensors.
The analog switch off happened to complete at the end of 2019. [41] Eswatini: The switchover is complete. [42] Gabon: All analog signals was turned off on 17 June 2016. [43] Ghana: Analog switch-off occurred in June 2015, switching to DVB-T. [44]
A video released as part of an ongoing lawsuit against Southern California Edison, the electrical utility for Los Angeles, appears to show what a law firm says is the start of the deadly Eaton Fire.
[1] [2] The term can be applied to a single switch or to an entire device. A simple example of holding current is in a Spark gap. In the most basic of circuits, if the current falls below the holding current even briefly, the circuit is turned 'OFF' (becomes blocked).
This can in turn cause a large pulse in the electric field across the open contacts, causing arcing and damage. It is often necessary to incorporate design features to limit such effects. Electronic devices such as vacuum tubes or valves, transistors, and diodes can also switch on and off very quickly, causing similar issues.
