I am not sure how to measure the current draw on a pulsed circuit, i would like to measure the maximum current draw during each pulse.
I have attached a quick diagram of how i think it is done, but i am unsure of what numbers i use or if i have it correct?
From the diagram we have a 10v pulse & the reading across the resistor, from the example is 2v with a 5 Ohm resistor.
First up, is this where you check the current from the pulse?
The big question is how then do i get the current measurement, i get 2v across the resistor so the voltage drop from the original 10v is 8v.
Do i use the 8v figure or the 2v figure?
I=V/R = 8v/5 Ohm = 1.6A
Or is it
I=V/R = 2v/5 Ohm = .4A
