Understanding Home Wiring and Grounding for Electrical Safety

The video tutorial explains the role of an electrician in setting up safe electric circuits in buildings. It describes modern wiring, which is typically covered in a tough rubber casing and contains copper wires. The video discusses the electric potential difference of 120 volts and the purpose of the ground wire. It explains how outlets and plugs function to complete circuits and highlights the importance of grounded plugs in preventing short circuits and reducing the risk of electric shock.
