Answer 2

easy bro, we know the seven fundamental units right?

They are meter (m), the kilogram (kg), the second (s), the kelvin (K), the ampere (A), the mole (mol), and the candela (cd).

you see the fundamental units have their own dimensional formula. for eg: metre's dimension is L

Second: T

candela: J or cd

temperature : K

so these fundamental units are fundamental dimensions

therefore Current has dimensional formula of [A] or [I]
