charge in circuits

• What is electrical charge measured in?

  Coulombs
• What does a current of 1 ampere represent?

  1 Coulomb of charge flowing per second
• How is the size of electric current defined?

  As the rate of flow of electrical charge
• What is the equation to calculate charge flow in coulombs?

  Charge flow = Current × Time
• How do you calculate the current if you know the charge flow and time?

  Current = Charge flow / Time
