Jätkpinge

Jätkpinge is a Finnish term that translates to "continuous voltage" or "holding voltage." It refers to the voltage required to maintain a current flow through a device or system once it has been initially energized or switched on. This is distinct from the initial voltage, often called "starting voltage" or "turn-on voltage," which is the higher voltage needed to overcome any initial resistance or to trigger a change in state.

In many electronic components, such as gas discharge tubes or certain types of relays, a higher voltage is necessary to initiate the discharge or activate the mechanism. Once this initial state is achieved, a lower, continuous voltage is sufficient to keep it in that state. This lower, continuous voltage is the jätkpinge. For example, in a neon lamp, a higher voltage is needed to strike the glow, but once it's glowing, a lower voltage will sustain the light.

The concept of jätkpinge is crucial in the design and operation of various electrical and electronic circuits. Understanding the difference between starting and holding voltages allows engineers to select appropriate power sources and components to ensure reliable and efficient operation. It also plays a role in power management, as maintaining a state at a lower voltage can lead to reduced energy consumption. Without the concept of jätkpinge, the operation of many devices would be either impossible or significantly less energy-efficient.
