Electric charge

• What is current?

  Electrical current is the flow of electric charges
• Flow of charge equation?

  current x time
• Current value in a single closed loop

  same value
• What is charge measured in?

  Coulombs
• what is an electrical insulator?

  material that doesn't allow electric current to pass through it
• electrical insulator examples

  plastic

  glass
• what is an electrical conductor?

  allows electrical current to pass through

  all metals
• What do electrical conductors have a lot of?

  Charges that are free to move

  in a metal, the charges that are free to move are electrons
• what is potential difference?

  Difference in the amount of energy that charge carriers have between two points in a circuit
