प्रश्न
What current will be taken by a 920 W appliance if the supply voltage is 230 V?
उत्तर
Given:
P = 920 W
V = 230 V
We know that power is given by P = VI, where I is the current consumed by the device.
Using the given values of P and V, we get:
920 = 230 I
I = `920/230=4A`
Thus, the current consumed by the appliance is 4 A.
