Human Harnessed Electricity
Human Harnessed Electricity
A moving electric charge is used in current electricity (human-harnessed electricity) where the flow of charged particles moves through a conductor.
This movement creates heat and magnetic fields.
Current electricity can be controlled in a predictable pattern through a circuit.
If electrons flow in a complete circuit, then energy can be harnessed and used to turn on a light bulb, cell phone, or any other electronic device.
Examples: Wind turbine, power plant, solar panels, dams
Naturally Occurring Electricity
Naturally Occurring Electricity
Static electricity, or naturally occurring electricity, is the build up of electrical charges on the surface of an object, resulting in an imbalance of positive and negative charges.
Produced by friction, or the resistance to motion as one object rubs against another object.
For example, when two objects, like a balloon and a piece of cloth, are rubbed together, some of the electrons, or charged particles, transfer and build up on one object causing it to have a different charge than before the interaction.
Depending on the electric charge of an object, it can attract or repel other objects.
Sometimes, the buildup of an electrical charge can jump from one object to another, or be discharged, through a small shock or spark.
Lightning is an example of large discharge of static electricity.
