Re: Circuit for measuring the current and voltage accros dio
do you need to embed that circuit in the circuit you want to measure, or will it be an external measuring circuit?

Circuit for measuring the current and voltage accros diode
would u like to see analog reading or digital?

Added after 3 minutes:

if u want analog measurement then use galvnometer in series with resistor and diode.. but if digitl then use sample and hold adc and seven sement decoder and display
