Conversion
Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field. There are two types of electric charge: positive and negative.
Charge Units Explained
- Coulomb (C): The SI derived unit of electric charge. It is the charge transported by a constant current of one ampere in one second.
- Ampere-hour (Ah): A unit of electric charge, equal to the charge transferred by a steady current of one ampere flowing for one hour, or 3,600 coulombs. Commonly seen on large batteries (like car batteries).
- Milliampere-hour (mAh): A unit of electric charge equal to 1/1000th of an ampere-hour. This is the standard unit for smartphone and laptop battery capacities.
[!TIP]
Fun Fact: One Coulomb is actually a huge amount of charge. A typical lightning bolt transfers about 15 Coulombs of charge. Your phone battery (e.g., 4000 mAh) holds about 14,400 Coulombs! The difference is lightning releases it in split seconds, your phone over hours.
