An electric oven of 2 kW power rating is operated in a domestic electric circuit [220V] that has a current rating of 5 A. What result do you expect ? Explain. |
|
Answer» SOLUTION : Given : Power of the oven = 2 kW = 2000W, Voltage = 220 V. Using P = VI , L = `(P)/(V) = (2000)/(220) = 9 . 09 A` This exceeds the specified current rating of the oven which is 5A . Hence electric fuse meltsand breaks the circuit. |
