In this tutorial I cover the following:

Power - the relationship with Voltage and Current
Power in watts = Volts x Amps (P=VI)
Power consumption in Wh = Power (Watts) x Time (hours)
Current consumption in Ah = Curent (Amps) x Time (hours)
Battery capacity
More energy / power efficient circuits
power consumption for BATTERIES
