An isolated conducting sphere of charge Q and radius R is grounded by using a high resistance wire. What is the amount of heat loss ?

Explanation

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)`
