Question

An electric bulb when connected across a power supply of 240 V consumes a power of 160 W. If the supply drops to 180 V, the power consumed would be

Answer 1

Answer:

If the supply drops supply is suddently increased to 240 V, what will be the power consumed? ,R = (V^2)/(P) = 220xx(220)/(60) = 806.67 Omega (a) E' = 180V P' = (V^2)/(R ) = 40.16 =40 W (b) E'' =240VP''= (V^2)/(R )=71.4 W= 71W`.
