How It Works
Electrical Charge
Electric charge is the fundamental quantity that defines the amount of electricity transferred.
Formula
Q = I * t
where I is the current in amperes and t is the time in seconds. One coulomb equals one ampere flowing for one second.
Worked Example
A circuit carrying 5 A for 60 seconds.
current = 5time = 60
- 01Q = I * t
- 02Q = 5 * 60
- 03Q = 300 C
- 04In mAh: 300 / 3.6 = 83.33 mAh
