SUMMARY
The discussion centers on calculating the start-up and operating current of an A/C starter using the back EMF equation. Given a 12V supply and a back EMF of 6V with a resistance of 0.1 ohms, the start-up current is calculated to be 120A, while the operating current is 60A. The equation used for these calculations is E=IR, where E represents voltage, I represents current, and R represents resistance.
