General Terms Table
To aid users in understanding and utilizing the mAh to mWh Calculator more effectively, here is a table of general terms commonly associated with battery capacity and energy conversion:
| Term | Definition |
|---|---|
| mAh | Milliampere-hour, a unit of electrical charge representing the capacity of a battery to store energy. |
| mWh | Milliwatt-hour, a unit of energy equivalent to one milliwatt (1/1000 of a watt) of power expended for one hour. |
| Voltage (V) | The electrical potential difference between two points, measured in volts. |
| Load Impedance (Z) | The opposition to the flow of alternating current in a circuit, measured in ohms. |
Example of mAh to mWh Calculator
Let's consider an example to illustrate how the mAh to mWh Calculator works:
Suppose we have a battery with a voltage of 3.7 volts and a load impedance of 50 ohms. Using the formula mentioned above:
Power (P) = (3.7^2) / (50 * 10^-6)
≈ 0.684 mWh
So, the power output of the battery is approximately 0.684 milliwatt-hours.
