Question

Explain that if two identical spherical conductors touch or are connected by conducting

wire, any excess charge will be shared equally.​

Answer 1

When the two conducting spheres are brought together to touch, it is as though they become one single big conductor and the total charge of the two spheres spreads out across the whole surface of the touching spheres. When the spheres are moved apart again, each one is left with half of the total original charge.
