R0 = 0.11?; and P is the power dissipated in the resistive element of the fuse. Determine the rated current at which the fuse will melt (that is, “blow”) and thus act as an open-circuit.

The resistive elements of fuses, lightbulbs, heaters, etc., are non-linear (i.e., the resistance is dependent on the current through the element). Assume the resistance of a fuse (Figure P2.45) is given by

R = R0[1 + A(T ? T0)] where: T ? T0 = kP;
T0 = 25°C; A = 0.7[?C]?1; k = 0.35°C/W;
(Hint: The fuse blows when R becomes infinite.)
