Answer to Question #33721 in Electric Circuits for rajiv jain
1.does the resistance of this device remain constant during its operation/working?
2.which of the two 100W,220V night lamps has higher resistance
(Because electric geyser is only resistor that's why phase between current and voltage is zero)
2) Two lamps have P=100 w, and V=220
R=220*220/100=484 ohm (the same resistance)
