I am designing a V/I Measurement device for a Geophysics application. In which we are applying 400Vp-p @1Hz square wave to two points (A & B)on earth (approx 50-80mtrs apart).
Now I want to measure current flowing through these two points on earth. How I can perform this measurement , i have done lot of research on current sense amplifier but didnot find any solution.
may be my idea of using current sense amplifier is wrong ? please suggest me how to do this, similarly i want to measure voltage between two intermediate points (c & d).
Please help me designing this Device. Thanks
Note: current would be of range from few uA to mA.
