two wires of equal diameters of resistivities row1 and row2 and lengths l1 and l2 respectively are joined in series the equivalent resistivity of the combination is
Dear Student,
Since the diameters of both the wires are same, they have same area of cross-section = a (say)
Resistance of 1st wire, ; Resistance of 2nd wire,
If connected in series,
