Vocabulary Words:
1. Electrical Current: electric charge in motion.
2. Conductor: is a material through which an electric charge can move easily.
Examples: Metals; cooper, gold and silver.
3. Insulator: is a material through which an electric charge moves with difficulty.
Examples: Plastic, rubber, glass, dry wood and eraser.
4. Series Circuit: electric charge can flow in only one circular path.
5. Parallel Circuit: has two or more paths through which electric charges may flow.
