Chapter 6 - Simple Circuits

Question 1

Electricity

Answer 1

Electricity is a form of energy, it is the movement of electrons.

Question 2

Electrons

Answer 2

Small negatively charged particles. Protons (positively charged) Neutrons (no charge) Electrons (negatively charged, light and orbits on the outside)

Question 3

Electric Charge

Answer 3

Electrons can be ‘knocked’ out of orbit, allowing them to move, this is called electricity.

Question 4

Static Electricity

Answer 4

The build up of electrons that have been displaced on a surface, by rubbing 2 surfaces together, electrons jump form negative surfaces to positive surfaces.

Question 5

Current Electricity

Answer 5

The flow of electrons along a conductor. This is what powers our electrical appliances, and is tranfered into kinectic erergy or heat energy.

Question 6

Electric Circuit

Answer 6

A path along which electrons travel and deliver their energy. It contains an energy source (power point or battery), an energy user (light bulb), and a conductor (wires)

Question 7

Closed and opened ciruits

Answer 7

A switch opens or closes the circuit. For electrons to flow it must be closed.
