The Art of Proper Wiring: A Guide

A close-up photo shows a person using a yellow digital multimeter to test a circuit. The multimeter's screen displays a negative voltage reading of -1.195. Red text overlays point to the test leads: one labeled 'positive' is connected to the negative terminal, and the other labeled 'negative' is connected to the positive terminal, with an arrow pointing to the screen labeled 'wrong wiring'. Another label points to the correct orientation of the leads. The setup includes a soldering iron and a black work mat.
