An electric oven consumes 1 kW electric power when operated at 220 v write the capacity of the fuse suitable for ur device .give reason for ur answer |

Answer» 5 AStep by step explanation:It is given that:P = 1 KWV = 220 VIt is REQUIRED to know the capacity of the fuse; which is the current.P = I*V1000 = I*220Therefore, the current FLOWING in the device; I = 1000/220 = 4.54 A Therefore, the fuse MUST be higher than 4.54 A because the function of the fuse is to protect a system from SHORT circuit current or HIGH currents.Therefore, I would suggest the fuse capacity to be 5 A. |
