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 43 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.30100 k
b.378 k
c.1627 k
d.814 k
e.1162 k
