1. Insulated Wires – Most wires are made of copper (a good conductor) and covered with plastic (an insulator) for safety.

2. Wire Stripping – The process of removing the plastic coating at the ends to expose the copper.

3. Wire Joint – The connection of two wires so that electricity can flow smoothly.

4. Insulation of Joints – Covering exposed copper with tape to prevent shock or short circuit.

 Golden Rule:
Electricity flows best through tight, clean joints. Loose joints = danger.
