Electricity

An electric current is:

• electricity

• the movement of electric charges inside a material

• an electrical property of particles

Polarity is:

• good and bad

• it's when you live in the North Pole

• a characteristic that differentiates the two sides of a direct current battery

Select only electric currents

• direct current

• energy

• alrternating current

• poles

the conductors:

• allow electric charges to move freely within it

• prevent electric accidents to occur

• open and close the circuit

An alternating current:

• always mantains the same direction of electric charges

• continually changes direction of electric charges

A generator is:

• a cord with small wires inside it

• an energy source that produces an electric current

• something that closes the circuit
