Question: The charging circuit for the flash system of a camera uses a 120?F capacitor that is charged from a 260V power supply.
A- What is the most resistance that can be in series with the capacitor if the capacitor is to charge to at least 88% of its final voltage in no more than 8.1s?
Answer should be in ohms
