The theoretical capacity of composite is equal to the theoretical capacity of each active component multiplied by their fraction

Anchali Jain

An-Giang Nguyen in case of coating of materials, the formula for finding theoretical capacity would be same?

Theoretically, it should be the same even for inactive material coating.

In particular, you may ignore coating materials if its fraction is negligible

Thanks An-Giang Nguyen
