Hello,
I am trying to measure the output and input power delivered to the circuit attached. I am aware that efficiency is output power/input power *100. I also know that to find the power, I can put a sense resistor in series with the output or input and measure the current/voltage across it and then use ohms law to find power.
Firstly, I'm wondering if my configuration in the attached diagram is correct? And if so, when measuring this with a DMM, do I need to take into account the resistance from the power supply and the resistance from the DMM?
Thanks in advance for your help!
