An electric current of 10 A is divided into three branches named branch1, branch2 and branch3, respectively, the lengths of the wires in the three branches being proportional to 1, 2 and 4. If wires of the same material and cross-section are used, what are the values of the currents in branch1, branch2 and branch3, respectively?
