The physics associated with spherically symmetric charged black holes is analyzed from the point of view of using weak gravitational lensing as a means for determining the dimensionality of spacetime. In particular, for exact solutions of electro-vac black holes in four and five spacetime dimensions the motion of photons is studied using the equations for the null geodesics and deriving the weak limit bending angles and delays in photon arrival times.
