What is the difference between average current and total charge?

Average Current is the total current consumption divided by the measured duration. No, that should read, "Average current is the total consumption divided by the measured duration." Current is charge per unit time so total charge will be current × time with units of (ampere-seconds).

What is the difference between average current and total current consumption?

"Average Current is the total current consumption divided by the measured duration" okay so if you have the total current consumption and you divide by the measured duration then you have the average. Do you have the total current consumption? Or do you have the average? If you already have the average why are you multiplying it by the duration?

What is the relationship between power and battery capacity?

The higher the power, the quicker the rate at which a battery can do work—this relationship shows how voltage and current are both important for working out what a battery is suitable for. Capacity = the power of the battery as a function of time, which is used to describe the length of time a battery will be able to power a device.

What happens if a battery has more than one charge?

But if there are more than one battery, the current entering and leaving the battery doesn't need to be same. Total charge could be divided in a such way that more charge ends up in one, less charge in other. But the total charge could be conserved again.

How do you calculate power capacity of a battery?

Power capacity is how much energy is stored in the battery. This power is often expressed in Watt-hours (the symbol Wh). A Watt-hour is the voltage (V) that the battery provides multiplied by how much current (Amps) the battery can provide for some amount of time (generally in hours). Voltage * Amps * hours = Wh.

What is battery power capacity?

Since this is a particularly confusing part of measuring batteries, I'm going to discuss it more in detail. Power capacity is how much energy is stored in the battery. This power is often expressed in Watt-hours (the symbol Wh).

9.6: Electrical Energy and Power
