The "pz220 & nbsp; 40" bulb works on a 220 volt circuit______ The power consumption per hour is 1 kilowatt hour, and the power of the circuit connected at 110 V is 0______ The rated power is______ Tile

The "pz220 & nbsp; 40" bulb works on a 220 volt circuit______ The power consumption per hour is 1 kilowatt hour, and the power of the circuit connected at 110 V is 0______ The rated power is______ Tile

T = WP = 10.04h = 25h. R = u2p = 220240 Ω & nbsp; = 1210 Ω. P1 = u21r = 11021210w = 10W. The rated power is known as 40W. So the answer is 25; 10; 40
