the largest moon

the moon closest to Jupiter
the moon farthest from Jupiter

I think it c the moon closest to Jupiter

Okay well gravitational energy is matter forced by gravity making energy though the kinetic energy then the electric energy produces electricity from the kinetic energy and the kinetic energy gets its energy from the gravitational energy. was that the answer you wanted or something else?  

Ametal with a large number of free flowing electrons most likely has good conductivity
