Modern society relies heavily on the convenience and versatility of electricity.
- It powers your microwave, helps light your house, lets you watch TV and so much more.
Electric current is measured in amperes (amps).
Electric potential energy is measured in volts.
Two positive charges repel each other, as do two negative charges.
- Opposite charges on the other hand attract each other.
When an electric charge builds up on the surface of an object it creates static electricity.
- You have probably experienced static electricity in the form of a small electric shock, which is what happens when the electric charge is quickly neutralized by an opposite charge.
Electric eels can produce strong electric shocks of around 500 volts for both self defense and hunting.
Electric circuits can contain parts such as switches, transformers, resistors and transformers.
A common way to produce electricity is by hydropower, a process that generates electricity by using water to spin turbines attached to generators.
