How To Calculate Battery Capacity?
The energy stored in a battery is calculated by multiplying the voltage of the battery by the capacity of the battery in ampere-hours. For example, a battery with a capacity of 1000 mAh and a voltage of 3.7 volts would have an energy storage capacity of 3.7 watt-hours (Wh).. It is important to note that battery capacity is not the same as the …

20.1: Current
Electric Current. Electric current is defined to be the rate at which charge flows. A large current, such as that used to start a truck engine, moves a large amount of charge in a small time, whereas a small current, such as that used to operate a hand-held calculator, moves a small amount of charge over a long period of time.
