Generators convert physical energy into B - Electrical energy

Explanation : Generator is a device which work on the electric mutual induction Which convert the mechanical energy ( physical energy ) to electric  energy.

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.

the components of a vector are the parts of the vectors that are to each other.
