Thanks for asking! We’re glad to help. I’m going to step you through with a few questions just to make sure we’re on the same page.
First of all, let’s set the stage. Both of these involve a circuit with two loads, and the voltage supply is shown as L1 – L2.
1. What is the total voltage supply for this circuit? (120vac or 240vac?)
2. What will the total voltage drop be for the entire circuit? (voltage drop for each load added together)
