The following table gives the current \( i \) (in amperes) through two devices for several values of potential difference \( V \) (in volts). From these data, determine which device does not obey Ohm's law.
\begin{tabular}{ccccc}
\hline \multicolumn{2}{c}{ Device 1 } & \multicolumn{2}{c}{ Device 2 } \\
\cline { 1 - 2 } \cline { 5 }\( V \) & \( i \) & \( V \) & \( i \) \\
\hline \( 2.00 \) & \( 4.50 \) & & \( 2.00 \) & \( 1.50 \) \\
\( 3.00 \) & \( 6.75 \) & & \( 3.00 \) & \( 2.20 \) \\
\( 4.00 \) & \( 9.00 \) & & \( 4.00 \) & \( 2.80 \) \\
