Electricity Flashcards

Flashcards about Electricity and Simple Circuits

What is electricity?

A form of energy caused by the movement of electrons.

What are electrons?

Small, negatively charged particles that orbit the nucleus of an atom.

What is the difference between static and current electricity?

Static electricity involves the build-up of electrons on a surface, while current electricity is the flow of electrons along a conductor.

How is static electricity achieved?

Rubbing two surfaces together, transferring electrons from one surface to another.

What happens to the build-up of electrons in static electricity?

The electrons dissipate slowly over time, or they jump to a positively charged surface, causing sparks, light, sound, or thermal energy.

Describe current electricity.

Current electricity is the flow of electrons along a conductor, commonly seen in copper wires powering appliances.

Into what forms of energy is electrical energy transformed?

Heat (toaster), light (bulbs), and kinetic energy (fans, motors).

What are the three basic components of an electrical circuit?

Energy source (battery), energy user (light bulb), and conductors (wires).

What is the difference between a closed and open circuit?

A closed circuit allows electrons to flow, while an open circuit prevents electron flow, turning off the appliance.

STATIC ELECTRICITY is the _ of electrons on a surface

Build up

CURRENT ELECTRICITY is the _ of electrons along a conductor e.g. copper wire

Flow

An ELECTRICAL is a path along which electrons travel and deliver their energy

Circuit

In a circuit, batteries and power points are examples of an ENERGY
