@embed12 This is all nonsense.
You have asked a question without giving any information that would help us give rational answers.
40mA 40kV
is by my reckoning 1.6kW of RF matched to a 1M load.
You cant use a resistive divider to measure RF, you need to account for the capacitance and inductance also.
So its NOT AC?
This starts to make a LITTLE more sense.
@Koepel gave you the answer in this post:
