The filament of a certain lamp has a resistance that increases linearly with temperature. when a constant voltage is switched on, the initial current decreases until the filament reaches its steady-state temperature. the temperature coefficient of resistivity of the filament is 4.5 times 10-3 k-1. the final current through the filament is one- eighth the initial current. what is the change in temperature of the filament?
a. 0100 k
b. 378 k
c. 1627 k
d. 814 k
e. 1162 k
