Efficiency in terms of power:
Efficiency = total power output/useful power input
Efficiency = useful power input/ total power input
Efficiency = useful power output/ total power input
Efficiency = total power input/ total power output
Equation linking power, energy and time
Power= energy/time
Power= energy x time
Energy= power/time
Power= energy/work done
Equation linking charge, time and current

Equation linking potential difference, current and resistance:
current = potential difference x resistance
potential difference = current x resistance
resistance = current x potential difference
potential difference = current / resistance
Power in terms of resistance and current
Power = current x resistance
Power= current / resistance
Power = (current)2/ resistance
Power = (current)2 x resistance
Power in terms of potential difference and current:
P = I x V
P = I / V
P = I x Q
