Electric Currents

When electrical charges build up, it creates

• static electricity

• connectors

• power sources

• charges

This is a steady flow of electric charges.

• electric generator

• closed loop

• wired connectors

• electric current

What three parts make up a simple circuit?

• power source, load, and connectors

• load, electric charges, and connectors

• power source, connectors, electric current

• connectors, power source, generator

What is the purpose of the power source in a simple circuit?

• The power source creates electricity.

• The power source gives energy to the circuit.

• The power source generates heat.

• The power source spins the blades in the turbine.

This type of circuit will transfer energy.

• closed loop

• open loop

• closed electric

• open electric

This is a device that uses an electric current to produce motion.

• steam engine

• motor

• turbine

• generator

This takes in energy carried by light.

• solar cell

• turbine

• electric current

• steam engine

What provides the energy for a solar cell?

• heat

• the sun
