💡 Charge Definition:
$$1\text{ Ah} = 3,600\text{ Coulombs} \implies 1\text{ mAh} = 3.6\text{ C} \implies 1\text{ F} = 96,485.33\text{ C}$$
Understanding Electric Charge & Battery Capacity
Electric charge ($Q$) is the physical property of matter that causes it to experience a force when placed in an electromagnetic field:
- SI Coulomb ($C$): $1\text{ Coulomb} = 1\text{ Ampere} \times 1\text{ second} = 6.2415 \times 10^{18}$ elementary charges.
- Battery Rating ($\text{mAh}$): A $5,000\text{ mAh}$ battery can deliver $5\text{ Amps}$ for 1 hour or $500\text{ mA}$ for 10 hours ($Q = 5000 \times 10^{-3} \times 3600 = 18,000\text{ C}$).
- Faraday Constant ($F$): $F = N_A \cdot e = 96,485.332\text{ C/mol}$ of electrons.
