Answer:

$C=2.54\cdot 10^5\ F$

Explanation:

<u>Energy Stored on a Capacitor</u>

This energy is stored in the electric field present when a voltage V is applied to a capacitor C. It can be computed by the formula

$\displaystyle E=\frac{CV^2}{2}$

We can compute the energy by knowing the power dissipated in the flashlamp is P=8 W in a time of $7 \mu s=7\cdot 10^{-6}\ sec$

$\displaystyle E=\frac{P}{t}=\frac{8\ W}{7\cdot 10^{-6}\ sec}=1.14\cdot 10^6\ J$

Solving the first equation for C

$\displaystyle C=\frac{2E}{V^2}$

$\displaystyle C=\frac{2\times 1.14\cdot 10^6}{3^2}$

$\boxed{C=2.54\cdot 10^5\ F}$
