Question: (a) If points a and b in Figure are connected by a wire of resistance r, show that the current in the wire is where

(a) If points a and b in Figure are connected by a wire of resistance r, show that the current in the wire is where ? is the emf of the ideal battery and R = R₁ = R₂. Assume that R₀ equals zero.

(b) Is this formula consistent with the result of Problem 55?

E(R, - R) (R + 2r)(R, + R) + 2R, R, Sliding

E(R, - R) (R + 2r)(R, + R) + 2R, R, Sliding contact R. R. ww
