As a result, the technology was successful in amplifying high-frequency current
to over two times the power of existing technology.
In inductive mold heating, an electrical coil passing high-frequency current
is placed near the mold surface to induce eddy current in the mold.
It uses a process called thermo-coagulation, whereby a high-frequency current
, applied via a needle, produces a thermal lesion in the vein yet does not damage the skin.
Lightning is a high-frequency current
, and that fact keeps you safe inside the metal skin of an aircraft either on the ground or in the sky.
Electrosurgery describes the act of coagulating or cutting by passing a high-frequency current
The machine which runs over the face - it looks rather like a tiny roller - emits a mild galvanic high-frequency current
to dig into the skin.
 Skin effect: A phenomenon observed when high-frequency current
is flowing through a conductor, where the higher the frequency, the more current tends to concentrate near the surface of the conductor.
Is 1 mA of high-frequency current
unreasonable to expect in the production environment?
Assume, as an example, that the system can tolerate 0.5 V of power/ground noise and that 0.5 A of high-frequency current
is being switched.
High-impedance arcs and corona generate high-frequency current
pulses that ride on the lower-frequency wave of the applied test-current waveform.
However, capacitors can actually increase the amount of high-frequency current
drawn by the source device.
This prevents damage to the motor's bearings from electrical currents induced in the shaft and frame of the motor by the high-frequency currents
in the VFD.
For RF and high-speed digital systems, SPG is not practical because the high-frequency currents
flow in the path with the least impedance, which always is through the distributed capacitance to the equipment chassis.
