Problem 4.141

A series circuit consisting of an inductance-free resistance \(R=0.16 \mathrm{k} \Omega\) and a coil with active resistance is coninected to the mains with effective voltage \(V=220 \mathrm{~V}\). Find the heat power generated in the coil if the effective voltage values across the resistance \(R\) and the coil are equal to \(V_{1}=80 \mathrm{~V}\) and \(V_{2}=180 \mathrm{~V}\) respectively.
