An isolated conducting sphere of charge Q and radius R is connected to a similar uncharged sphere (kept at a large distance) by using a high resistance wire. After a long time is the amount of heat loss?

Explanation

When two conducting spheres of equal radius are connected charge is equally distributed on them (Result VI). So we can say that heat loss of system
`Delta H = U_(i) - U_(f)`
`= ((Q^(2))/(8pi epsilon_(0)R) - 0) - ((Q^(2)//4)/(8pi epsilon_(0)R) + (Q^(2)//4)/(8pi epsilon_(0)R)) = (Q^(2))/(16 pi epsilon_(0)R)`
