The flash unit in a camera utilizes a 2V battery to charge a capacitor. The capacitor is then discharged through a flash lamp. The discharge takes 10s, and the average power dissipated in the flash lamp is 10 W.
Part A
What is the capacitance of the capacitor?
Express your answer with the appropriate units.
