What is the practical unit of electric charge? Why is this unit used?
1 Answer
Although the SI unit of charge is the Coulomb (
Explanation:
The Coulomb,
In low power applications, particularly those where batteries are used, it is more practical to work with a much lower current, over a much longer time. For that purpose one uses the milliamp-hour.
Typical mobile phone batteries have on the order of thousands of
For higher power applications, one sometimes uses Amp-hours (
