Study Notes
Electrical Insulators
- Insulators prevent the flow of electricity.
- Insulators are materials with tightly bound electrons that restrict electron movement.
- Examples include rubber, wood, plastic, wool, silk, fur, oil, paper, and glass.
- Insulators, like security guards, prevent electricity from passing through.
Electrical Conductors
- Conductors allow the flow of electricity.
- Conductors are materials with loosely bound electrons that allow free electron movement.
- Examples include copper, silver, aluminum, nickel, iron, and paperclips.
- Conductors, like open doors, allow electricity to move through.
Electricity Transfer
- Electrons, negatively charged particles, are necessary for electricity.
- Free electron movement is key for the electricity to flow.
- Materials with tightly bound electrons restrict electron movement, hence they act as insulators.
- Materials with loosely bound electrons allow free electron movement, hence they act as conductors.
Electrocution
- Electrocution is the potentially deadly outcome of a powerful electric shock.
- Electrical wires are often insulated to prevent shock hazard.
- Insulators block dangerous current flow.
Semi-Conductors
- Some, like humans, are semi-conductors.
- Semi-conductors allow some but not as free electron movement as conductors.
- The human body can distribute charge, like from a Van de Graaff generator.
