Electrical Charge and Current

• What is electric current?

  A flow of electrical charge
• How is the size of electric current defined?

  It is the rate of flow of charge
• What does it mean that current has the same value at any point in a closed series circuit?

  Charge is conserved throughout the circuit
• What is the relationship between electric charge and current?

  • Electric current is a flow of electric charge.
  • The size of current is the rate of flow of charge.
