Power

• What is power?

  The energy transferred per second. It is directly proportional to current and voltage
• Power loss is proportional to resistance, and to the square of the current
• What is the equation linking energy transferred, power and time?

  energy transferred = Power x time

  E = Pt
• What is the equation linking energy transferred, charge and potential difference?

  energy transferred = charge x potential difference

  E = QV
