You have a 2.0-uF capacitor and a 9.0-V battery: 2a. If initially uncharged, how long does it take to charge the capacitor to 80% of its maximum voltage through a 1.5-M2 resistor? Assume its maximum voltage is the same as the battery. 2b. If initially fully charged, how long would it take to discharge the capacitor to 30% of its maximum voltage through a 2.4-MΩ resistor?
In the circuit below, E = 11 V, R1 = 5.6 kOhm, R2 = 1.2 kOhm , C = 60 uF Initially the capacitor is fully charged. At t = 0 the switch moves to position B. How long does it take for the capacitor to reach 300 mV?
The figure shows a simplified circuit for a photographic flash unit. This circuit consists of a 9.0-V battery, a 50.0-kO resistor, a 140-µF capacitor, a flashbulb, andtwo switches. Initially, the capacitor is uncharged and the two switches are open. To charge the unit, switch S1is closed; to fire the flash, switch S2(which is connected to the camera's shutter) is closed.How long does it take to charge the capacitor to 5.0V ?http://session.masteringphysics.com/problemAsset/1122589/1/Walker.21.66.jpg
