The figure (Eigure.1) shows a simplified circuit for a photographic flash unit. This circuit consists of a 9.0-V battery, a 50.0-k resistor, a 140-F capacitor, a fashbulb, and two switches. Initially, the capacitor is uncharged and the two switches are open. To charge the unit, switch S, is closed; to fire the fash, switch S (which is connected to the camera's shutter) is closed Figure 9.0V 500 kn 140µF tol1 Part A How long does it take to charge the capacitor to 6.0V?
