Source ACIs this school work?
Is the source AC or DC? What does the green squiggle connect to? Does the black arrow represent ground?
If this represents a HBM (Human Body Model). The KV source is the human body. The 50Mhom resistor represents the human body ability to charge to high voltages via ES build up. The capacitor represents that amount of charged held by the human body. The switch when closed represents an ESD event. Basically, an ESD event is a large discharge from a high voltage capacitor, the capacitor itself representing the human body.May i know how does this circuit function??
If the switch does close it will short the AC source. Good luck with that if is connected to the generators at Hoover dam. If it does represent the HBM, then the discharge current is relatively insignificant and 5 RC time constants is like 250 ns.Cap isn't going to have much charge with an AC source. It'll be constantly charging and discharging.
I guess somebody must think it would be a distraction.If the source is AC, it is a low pass filter with, basically, a short to ground switched in.
I think that is highly unlikely.
Does anyone else wonder what the rest of the picture shows? Clearly it has been cropped.
