noise can get coupled to the circuit via capacitive coupling. now suppose if we take an example of normal power lines(50/60 Hz) . now if we place our board(which has wires ~1m) can we get an approximate value of the coupling capacitor between the 50hz and the wire. the distance between the the board wires and the power lines ~3m.
i think it should be inversely proportional to distance between them(power line and board wire), and proportional to the current in the board wire, board wire length.but how to get an approximated value of the coupling capacitor.
