The flash unit in a camera uses a special circuit to "step up" the 3.0 V from the batteries to 270 V , which charges a capacitor. The capacitor is then discharged through a flashlamp. The discharge takes 11 μs , and the average power dissipated in the flashlamp is 1.0×10^5 W . What is the capacitance of the capacitor?
The flash unit in a camera uses a special circuit to "step up" the 3.0 V from the batteries to 360 V , which charges a capacitor. The capacitor is then discharged through a flashlamp. The discharge takes 12 μs , and the average power dissipated in the flashlamp is 1.0×105 W . What is the capacitance of the capacitor? use 2 sigfigs I have tried 0.27 F and 0.26 F but so far both are wrong on mastering physics.
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.
Capacitors are used in many applications where one needs to supply a short burst of relatively large current. A 164-μF capacitor in an electronic flash lamp supplies a burst of current that dissipates 10.1 J of energy (as light and heat) in the lamp. To what potential difference must the capacitor initially be charged? What is its initial charge? Approximately what is the resistance of the lamp if the current reaches 5.00% of its original value in 1.37 ms?
