Answer the questions on the
P basis of your understanding of the following table and

W related studied concepts:
\begin{tabular}{l|l}
\hline Name of the appliances & Power \\
\hline Television & \( 230 \mathrm{~W} \) \\
\hline Light bulbs & \( 60 \mathrm{~W}, 100 \mathrm{~W} \) \\
\hline Amplifier & \( 180 \mathrm{~W} \) \\
\hline Refrigerator & \( 150 \mathrm{~W} \) \\
\hline Electric iron & \( 750 \mathrm{~W} \) \\
\hline Electric kettle & \( 2 \mathrm{~kW} \) \\
\hline Immersion heater & \( 3 \mathrm{~kW} \) \\
\hline Cooker & \( 8 \mathrm{~kW} \) \\
\hline
\end{tabular}
For an electric iron, calculate the maximum amount of current and the number of units of electricity, it would use in \( 30 \mathrm{~min} \) from above table.
