Introduction to Electricity Physical Science

An electrical charge is a property of matter. There are two types of electrical charges, positive and negative.

• True

• False

The build up of electrical charges on an object.

• electricity

• electrical charge

• Static electricity

• negative charge

The movement of static electricity from one object to another.

• positive charge

• insulators

• conductors

• discharge

Materials that allow charges to flow through them easily. For example, metal is a ____________.

• insulator

• conductor

• discharge

• static electricity

Materials that do not let charges flow through them easily. For example, wood is a __________.

• conductor

• discharge

• insulator

• electricity

Electrical charges can be made to to flow continuously through materials. A flow of electrical charges in known as _________.

• voltage

• electric current

• static electricity

• circuit

The path along which electrical current flows.

• insulator

• voltage

• conductor

• circuit

All of the electrical charges flow in the same direction along a single path.

• parallel circuit

• series circuit

• electrical current

• resistance

A circuit on which the electrical current flows through more than one path.

• parallel circuit

• voltage

• series circuit

• resistance

The strength of a power source.
