Physics - Current Electricity Question with Solution | TestHub

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