I have a sense resistor connected in series with the neutral wire.
From the oscilloscope i detect noise of around 500mV - 1V across the sense resistor at high frequencies 60khz- 100khz. I see the noise once the power plug is inserted to the socket, although not switched on(live wire not connected). It seems to have quite an amount of current going through the neutral wire itself.
The source is a 240V 60Hz single phase.
Is this possible?
