Hi All, I came across a design where the system field ground connected with mounting hole with 3 to 4 series of resistor of 100K which intern connected to chassis ground. If i look into this circuit these series resistor contributes a high value of resistance between the system GND and chassis ground, we often short the system GND and chassis GND using Inductor. Can anyone explain what strategy behind this? Thanks, Raj. ____________________________________________________________________________________ Sponsored Link $420k for $1,399/mo.
