A family circuit is equipped with four "220 V & nbsp; & nbsp; 40 W" lamps, one electric fan with 60 W power, one electric fan with 100 W power and one refrigerator with 100 W power?

A family circuit is equipped with four "220 V & nbsp; & nbsp; 40 W" lamps, one electric fan with 60 W power, one electric fan with 100 W power and one refrigerator with 100 W power?

It is known that P1 = 40W, P2 = 60W, P3 = 100W, P4 = 100W, u = 220V, P = 4p1 + P2 + P3 + P4 = 4 × 40W + 60W + 100W + 100W = 420W, I = Pu = 420w220 V ≈ 1.91a
