Step 1: Definition of Capacitor

The energy stored in a capacitance C capacitor charged to a potential difference $ΔV$ is as follows:

$U_{E} = \frac{1}{2} C (ΔV)^{2}$

Step 2: Given information

The capacitor's capacitance is: $\begin{array}{rcl} C & = & (165 μF) (\frac{1 F}{10^{6} μF}) \\ = & 165 \times 10^{- 6} F \end{array}$

The capacitance's potential difference is: $ΔV = 119 V$

Step 3: Finding the energy stored in the capacitor

The amount of energy stored in the capacitor can be found from the equation:

$U_{E} = \frac{1}{2} C (ΔV)^{2}$

Now, substitute the values of C and $∆ V$

We get,

$\begin{array}{rcl} U_{E} & = & \frac{1}{2} (165 \times 10^{- 6} F) (119 V)^{2} \\ = & 1.17 J \end{array}$

Therefore, the energy stored in the capacitor is 1.17 J.
