current electricity

What is voltage?

• the rate of flow of charge

• the difference in charge between 2 points

• the amount of available charge

What is an electric current?

• a build up of electrons

• the difference in charge between 2 points

• the flow of electrons through a circuit

• the opposition to flow of electrons

What is resistance

• the rate at which a charge is flowing

• the material's tendency to resist flow of electrons

• the difference of charge between 2 points

• it is futile
