The RC charging circuit in a camera flash unit has a voltage source of 265 V and a capacitance of 141 µF. HINT (a) Find its resistance R (in ohms) if the capacitor charges to 90.0% of its final value in 16.7 s. Q (b) Find the average current (in A) delivered to the flash bulb if the capacitor discharges 90.0% of its full charge in 1.44 ms.
