Hi guys, newbie here. Good to see a forum like this.
So here is my first question.
I have an Oscope. I wanted to know the peak current that was being pulled by a DC motor under load.
When I hooked up the Oscope, I was expecting a clean jump on the screen where the voltage line went from 0 to whatever voltage.
What I saw was spikes of all sorts at high resolution of the X - Axis.
Also, the math is showing that the current is 48 Amps, which can't be, since the power supply that was running the motor could give out only a max of 30 Amps.
How would one go about calculating the voltage in this case?
Thx
