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 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 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...
The RC charging circuit in a camera flash unit has a voltage
source of 275 V and a capacitance of 125F.
Find its resistance R if the capacitor charges to 90% of its
final value in 15 s.
Find the average current delivered to the flash bulb if the
capacitor discharges 90% of its full charge in 1.00 ms.
