Electric Circuits Test

What is a conductor?

•  A material that allows electricity to flow through it.  The circuit is complete. 
• A material that does not allow electricity to flow through.  It stops the flow of electricity.
• A light switch.
• The person who stands in front of an orchestra.

An incomplete circuit is shown.
To complete the circuit, a wire should be placed from —

• Point D to Point C
• Point B to Point C
• Point A to Point D
• Point B to Point D

The electrician in this picture is wearing rubber gloves for protection.  The purpose of the rubber gloves is to --

• keep the electrician dry
• create an electrical circuit
• produce electricity
• protect the electrician

What is an INSULATOR?

•  A material that allows electricity to flow through it.  The circuit is complete. 
• A material that does not allow electricity to flow through.  It stops the flow of electricity.
• A light switch.
• A material that is magnetic.

What is an ELECTRIC CURRENT?

• The flow of charged particles in one direction.

• The flow of water in a river.

• When particles stick to each other.

• When electric energy is transferred into light energy.

What is ELECTRIC CHARGE?

• A force caused by the movement of my car.

• A force caused by the movement of river currents.

• A force caused by the movement of negative and positive particles.

• A force caused by the temperature of an object increasing.
