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?

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