electricity

• charge flow :

  charge flow = current × time

  Q = l × t
• potential difference

  • potential difference = current × resistance
  • v = l × R
• total resistance

  • total resistance = resistance of component 1 + resistance of component 2
• power (using pd)

  • power = current × potential difference
  • p = l × v
• power (resistance)

  • power = (current) squared × resistance
  • p = l $^2$ × R
• energy transferred

  • energy transferred = power × time
  • E = p × t
• energy transferred

  • energy transferred = charge flow × potential difference
  • E = Q × V
