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
