Two copper spheres have the radii of R and 3R and are located far away from each other. In the first experiment, an initial charge +Q is placed on each sphere. The spheres are then connected by a thin straight wire. It is discovered that maximum current through the wire is I0. In the second experiment, the larger sphere has the initial charge +Q, and the smaller one is neutral. The spheres are then connected by the same wire. What would be the maximum current I through the wire this time?

We received a large number of solutions to our February ChallengePerformance under pressure. We are pleased to recognize the following contributors:

Many thanks to all contributors and we hope to hear from many more of you in the future!

Note: as always, we would very much appreciate...
