• What is one formula for energy?

  Energy (E) = Power (P) x Time (t)

  E=Pt
• What is a second formula for energy?

  Energy (E) = Voltage (V) x Current (I) x Time (t)

  E=VIt
• What is a third formula for energy?

  Energy (E) = Charge (Q) x Voltage (V)

  E=QV
• What is one formula for power?


  Power (P) = Current (I) x Voltage (V)

  P=IV
• What is a second formula for power?

  Power = Current2 x Resistance
