The flash unit in a camera uses a special circuit to "step up" the 3.0 V from the batteries to 320 V, which charges a capacitor. The capacitor is then discharged through a flashlamp. The discharge takes 12 mu s, and the average power dissipated in the flashlamp is 1.0 times 10^5 W. What is the capacitance of the capacitor? Express your answer to two significant figures and include the appropriate units.

5. AM: Capacitors are used in many applications where you need to supply a short burst of energy, for example, a mobile defibrillator or a camera's flashlamp. The flash unit in a camera uses a special circuit to “step up” the 3.0 V from the batteries to 300 V, and the 300 V charges a capacitor (otherwise the 3.0 V battery would take very long time to charge the capacitor). The capacitor is then discharged through a flashlamp. The discharge...

Problem 8.4-6 3 v 80k 2 uF + Harold E. Edgerton invented the electronic flash. An electronic flash on a camera uses the circuit shown above. Let's call the time at which the shutter switch is pressed t = 0. Before time t = 0, the capacitor charges to 3 volts. When the shutter switch is pressed the switch in this circuit moves to the right causing a current in the 80-822 resistor that represents the flash. The discharge of...
