Q. 24.6( 53 Votes )

An electric oven of 2 kW power rating is operated in a domestic electric circuit (220 V) that has a current rating of 5 A. What result do you expect? Explain.

Answer :

We will first calculate the Current drawn by the oven,

Given,  Power(P)= 2kW
                   = 2x 1000 W
                   = 2000 W
          
           Voltage(V)= 220V
          
            We know P= V x I

    Therefore the current drawn(I)=   

                                               =  9 A

The Current drawn by the electric oven is 9 Amperes which is high as compared to the fuse in the electric circuit which is of only 5 Amperes as a result the fuse will blow off cutting of the power supply when the electric oven will operate.
