Question

Five electric fans of 120 watts each are used for4 hours,Calculate the electrical energy consumed in Killowatt hours​

Answer 1

Step-by-step explanation:

Answer : 2.4 kWh

Step-by-step explanation :

Since we know that,

1 W = 1/1000 kW

120 W = 120/1000 kW

= 0.12 kW

Such power has been consumed by 5 electric fans,

= 5 × 0.12 kW = 0.6 kW

This energy has been consumed for 4 hours

= 0.6 kW × 4 hrs = 2.4 kWh

So energy consumed = 2.4 kWh
