Sample Calculation for Power

The following calculation shows how the power was obtained. Note that this value is proportional to power, but it not the value for power itself.

$$\begin{eqnarray*} P & \propto & V^2 \\ & \propto & (0.0017V-0.0004V)^2 \\ & \propto & 1.69\times10^{-6} V^2 \end{eqnarray*}$$
