The RC charging circuit in a camera flash unit has a voltage source of 305 V and a capacitance of 126 F.
a)
Find its resistance R (in ohms) if the capacitor charges to 90.0% of its final value in 12.7 s.
b)Find the average current (in A) delivered to the flash bulb if the capacitor discharges 90.0% of its full charge in 1.14 ms.
