Electricity travels at the speed of light - more than 186,000 miles per second!
A spark of static electricity can measure up to three thousand (3,000) volts.
A bolt of lightning can measure up to three million (3,000,000) volts, and it lasts less than one second!
We use electricity everyday, but most people know very little about the physical phenomena. Electricity is the most versatile energy source on the planet, but we’ve only depended on it for about 100 years.
Electricity is a type of energy that builds up in one place, or flows from one place to another. When electricity gathers in one place it is known as static electricity. Electricity that moves from one place to another is called electric current.
Static electricity usually happens when you rub things together. It’s why a balloon will stick to you after rubbing it against your clothes. Or why you get a shock when walking across carpet and touching something metallic. It’s also the cause of lightning. As rain clouds move through the sky, they rub against the air around them.
An electric current is a flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire. It is involved in powering the electrical appliances you use every day: computers, smartphones, washing machines, flashlights and any other common electric device.
Here are a few more cool facts about electricity:
1. Electricity travels at 6,696,000 miles per hour.
2. Electricity plays an important role in the way your heart functions. Muscle cells in the heart are contracted by electricity that runs through your body.Medical-Equipment-ECG-Monitor
Electrocardiogram (ECG) machines are used in hospitals to measure the electricity flowing through a patient’s heart, displaying a line that spikes with every heartbeat.
