In electrical and electronics engineering, wetting current is the minimum electric current needing to flow through a contact to break through the surface film resistance at a contact. [1] It is typically far below the contact's nominal maximum current rating.
Marx generator A kind of circuit for generating very high DC voltage pulses. Maser A device that produces microwave energy in a similar manner to a LASER. maximum prospective short-circuit current The calculated value of current that could flow if a short circuit occurred; a parameter for selection of circuit protection devices. Maxwell's equations
Because of this, alternative materials that can be used to coat and functionalize the surface are used to create the expected wetting behavior. For example, amorphous fluoropolymers are widely used electrowetting coating materials, and it has been found that the behavior of these fluoropolymers can be enhanced by the appropriate surface patterning.
A generator in electrical circuit theory is one of two ideal elements: an ideal voltage source, or an ideal current source. [1] These are two of the fundamental elements in circuit theory. Real electrical generators are most commonly modelled as a non-ideal source consisting of a combination of an ideal source and a resistor.
The result is a rapidly pulsed electric current instead of a clean transition from zero to full current. The effect is usually unimportant in power circuits, but causes problems in some analogue and logic circuits that respond fast enough to misinterpret the on‑off pulses as a data stream. [5]
A current source is an electronic circuit that delivers or absorbs an electric current which is independent of the voltage across it. A current source is the dual of a voltage source. The term current sink is sometimes used for sources fed from a negative voltage supply.

Current limiting is the practice of imposing a limit on the current that may be delivered to a load to protect the circuit generating or transmitting the current from harmful effects due to a short-circuit or overload. The term "current limiting" is also used to define a type of overcurrent protective device.
