We study the multifractal spectrum of the current in the two-dimensional random resistor network at the percolation threshold. We consider two ways of applying the voltage difference: (i) two parallel bars, and (ii) two points. Our numerical results suggest that in the infinite system limit, the probability distribution behaves for small i as [Formula Presented] where i is the current. As a consequence, the moments of i of order [Formula Presented] do not exist and all currents of value below the most probable one have the fractal dimension of the backbone. The backbone can thus be described in terms of only (i) blobs of fractal dimension [Formula Presented] and (ii) high current carrying bonds of fractal dimension going from [Formula Presented] to [Formula Presented]
