high-fre·quen·cy cur·rent

an alternating electric current having a frequency of 10,000 or more cycles per second; it produces no muscular contractions and does not affect the sensory nerves.

The injection mold with these attributes is thus subjected to the proximity effect when high-frequency current is applied.
Our students are given a design problem requiring them to protect sensitive analog components (usually audio amplifiers or phase-locked loop oscillators) from digital circuitry by gapping the return plane in such a way that the low-frequency currents are isolated and the high-frequency currents are not impeded.
It was also the first paper on high-frequency currents in the world [8].
There he met Jacques-Arsene d Arsonval, a French physician, who conducted experiments with high-frequency currents, denying the feet that Tesla released observations of physiological effects of these current before him [5].
They both sent him their books on the treatment using high-frequency currents, but Tesla corrected them on several occasions that the discovery of these currents was wrongly attributed to William James Morton, and the discovery of their therapeutic activity to d Arsonval [3].
Monell also emphasizes that the main effect of high-frequency currents is based on their power to "modify the natural physiological processes in the body" [9, 16].
At the stage of drafting the book, in a letter dated June 4, 1909, Monell wrote to Tesla about his ideas on the cooperation related to the design, manufacture and marketing of devices based on Tesla's high-frequency currents [16].
According to this author, Tesla designed a device with high-frequency currents in a wardrobe of a New York theatre, for actors suffering from stage fright [21].
Conducted emissions are caused when high-frequency currents flow back through the input lines, polluting the power source lines or power grid.
These conductors can be the line and neutral power input lines (the radiated emissions being the radiated result of the high-frequency currents in these lines) or virtually any other set of conductors within the power supply.
