A series circuit consisting of an inductance-free resistance R = 0.16 kS and a coil with active resistance is connected to the mains with effective voltage V = 220 V, Find the heat power generated in the coil if the effective voltage values across the resistance R and the coil are equal to V1 = 80 V and V2 = 180 V respectively.

Solution:
A series circuit consisting of an inductance-free resistance R = 0.16 kS and a c
