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.
