Perhaps a silly question but...
I have two comparable circuits which take AC in and give DC out. The AC in is a small transformer which gives out 7.9V AC RMS and which drops to 7.30 with a load attached. The circuits give out 5.00V, though one is 4.94 and drops to 4.89 under load.
Should I be measuring the voltage drop values for the efficiency calculation?
