Study Notes
Electricity: A Summary
- Electricity is a form of energy used by everyday appliances like computers, phones, and televisions.
- Electricity needs a conductor to flow, which allows it to move through the material.
- The human body can be a conductor, causing shocks if electricity travels through it.
- Electrical shocks can be dangerous, causing muscle tightening, breathing difficulties, and burns.
Electrical Safety at Home
- Electrical outlets should be covered with safety caps when not in use.
- Do not insert objects like fingers into electrical outlets.
- Always ask an adult for help when using electricity or unplugging appliances.
- Never yank cords when unplugging appliances, but rather pull the cord gently.
- Keep electrical cords organized and neatly tucked away.
- Make sure to turn off the light fixture before changing a blown bulb.
Electrical Safety Outdoors
- Avoid touching utility poles and power lines.
- Stay away from utility poles and power lines when playing outdoors, especially with kites or climbing trees.
- Seek shelter during thunderstorms to avoid lightning, a powerful form of electricity.
- Get out of water immediately if a thunderstorm approaches – water is a conductor.
- If you see a fallen power line, call 911 immediately; never touch the fallen wire or the person impacted.
