Calculate Resistance R = (V)/(I) for each data point.

Here are the calculations for $R$ and $1/R$ based on the provided data.

Step 1: Calculate Resistance $R = \frac{V}{I}$ for each data point.

Step 2: Calculate the Inverse of Resistance $\frac{1}{R}$ for each data point.

The completed table is as follows:

\begin{array}{|c|c|c|c|} \hline Current I (A) & Voltage V (V) & R = \frac{V}{I} (\Omega) & \frac{1}{R} (\Omega
