It contains a switch, two lightbulbs, a variable resistor (varistor) and a fuse. \\\\ The second circuit starts with an Ampmeter, and in series to that there are a Voltmeter and a Lightbulb in parallel. \section{Book p.26} \subsection{Task 1} \subsubsection{Subtask A} \begin{center} \begin{tabular}{c|c} Image 1 & Multimeter \\\hline Image 2 & Electric Drill \\\hline Image 3 & Mallet \\\hline Image 4 & Allen Keys \\\hline Image 5 & Vernier Calipers \\\hline Image 6 & Phillips Screwdriver \\\hline Image 7 & Flat-Bladed Screwdriver \\\hline Image 8 & Angle Grinder \\\hline Image 9 & Open-Ended Spanner \\\hline Image 10 & Hacksaw \\\hline Image 11 & Drill \\\hline Image 12 & Extension Reel \\\hline Image 13 & Wire Strippers \\\hline Image 14 & Combination Pliers \\\hline Image 15 & Chisel \\\hline Image 16 & Ring Spanner \\\hline Image 17 & Side-Cutters \\\hline Image 18 & Crimping Pliers \\\hline Image 19 & Soldering Iron \\\hline Image 20 & Voltage Tester \end{tabular} \end{center} \end{document}
