(non-conducting, of course) spherical shell has radiusaand is centered onthe origin. the upper half (z > 0 orθ < π2) has a chargequniformly distributed on itssurface, and the lower half has a charge−quniformly distributed on its surface. find thepotential both inside and outside the sphere, up to fifth order in cosθ. hint: think aboutthe symmetry of the boundary conditions here with respect to the ‘equator’ (θ=π/2) –can you rule out any legendre polynomials from appearing in your solution?

Ohm's law tells you that i = v/r where v is equivalent voltage and r is equivalent resistance of the circuit
since all circuits have the same voltage, your question is really asking which circuit has the lowest total resistance, since the lower the resistance, the higher the current
circuit a has a resistance of 5 ohms; circuit c is in series so has a resistance of 10 ohms; circuit b is in parallel and therefore has a resistance of 2.5 ohms (review your notes on adding resistances in parallel and series); therefore b has the highest current
