The figure shows a simplified circuit for a photographic flashunit. This circuit consists of a 9.0-V battery, a 50.0-kO resistor,a 140-µF capacitor, a flashbulb, and two switches. Initially, thecapacitor is uncharged and the two switches are open. To charge theunit, switch S1 is closed; to fire the flash, switch S2 (which isconnected to the camera's shutter) is closed.How long does it taketo charge the capacitor to 5.0V ?
