Average value for a function -Battary Charge Example

Описание: This video explains how to find the average value of a function using definite integrals, demonstrated through a practical real-life example involving battery charging behavior.
With smooth animations, a thick and clear xy–plane, and slow, easy-to-follow narration, this lesson connects calculus with everyday technology.

Real-Life Example: Battery Charge Rate

Modern batteries do not charge at a constant rate.
Instead, the charging speed varies over time depending on:

Temperature
Battery health
Charging mode
Protection circuits

In this video:
A function represents the instantaneous charging rate of a battery over time.
Using the average value formula, we determine the average charging speed over a specific interval.
This helps explain why some parts of the charging process are fast and others slow.
