Choose the energy that is described below.

Wind turbines are turned by the wind. As the turbines turn, they spin a generator. The motion creates energy, which converts into electricity.

• WInd

• Solar

• Hydropower (water)

• Biomass

• Human power.

Would would best complete this circuit?

• A wire

• A switch

• A battery

• A light bulb

The fuse in a circuit melts when:

• An appliance isn't earthed

• Too much current flows

• Too much voltage flows

It is a good idea to not plug too many things into one outlet, since there is a risk of overloading the circuit at that outlet.

• true

• false
