1. The problem statement, all variables and given/known data A conducting sphere of radius a is surrounded by a neutral conducting shell of radius b (b > a).Connections are provided as shown in diagram. Initially, the sphere has a charge Q. The switch S1 is opened and then closed. The switch S2 is then opened and closed. Finally, the switch S3 is closed. What is the heat energy dissipated in the system after S3 is closed? 2. Relevant equations E = k Qq/r2 V = k Qq/r 3. The attempt at a solution Work done is equal to the product of the charge and the potential difference. So it's my guess that, after switch S3 is opened, the product of the charge difference and the potential difference between the sphere and the shell IS the heat energy produced. However,this idea has only confused me all the more,and I don't even have a glint of how to proceed with the sum. (I am familiar with Gauss's law for electrostatics).
