Q
Efficiency
A
efficiency = useful output energy transfer / total input energy transfer
3
Q
Potential Difference
A
potential difference = current x resistance
4
Q
Power
A
power = energy transferred / time

A
Efficiency = useful power output / total power input
6
Q
Energy Transferred
A
energy transferred = power x time
7
Q
Power (Potential Difference)
A
power = potential difference x current
8
Q
Energy Transferred (Charge Flow)
A
Energy Transferred = charge flow x potential difference
9
Q
Power (Current)
A
power = (current)^2 x resistance
