Units for charge
Section titled “Units for charge”There are two main ways we can measure charge:
- Coulombs (C): The SI unit. One coulomb is equal to one ampere-second (As).
- Milliampere-hours (mAh): This is commonoly used for batteries -
.
Coulom
Section titled “Coulom”-
One coulomb is equal to
electrons! It’s an easier way to measure charge than counting the septillions of electrons.
Example: Convert 5000mAh to coulombs
Section titled “Example: Convert 5000mAh to coulombs”- mAh -> C = x3.6
