The flash unit in a camera uses a special circuit to "step up" the 3.0 V from the batteries to 370 V, which charges a capacitor The capacitor is then discharged through a flashlamp. The discharge takes 10 microseconds, and the average power dissipated in the flashlamp is 11W .
What is the capacitance of the capacitor?
