Question

An electric toaster has resistance of $$60 \, \Omega$$ at room temperature ($$27^\circ 	ext{C}$$). The toaster is connected to a $$220 \, 	ext{V}$$ supply. If the current flowing through it reaches $$2.75 \, 	ext{A}$$, the temperature attained by toaster is around: (if $$\alpha = 2	imes 10^{-4} \, ^\circ 	ext{C}^{-1}$$)
