Answer 2

Answer:

Electrical energy would consumed in kWh is 1.96 kWh.

Explanation:

Given:

An electric bulb of 100W is lighted for 2 hours and a fan of 110W is used for one hour.

To Find:

How much electrical energy would be consumed in kWh ?

Solution:

We know that,

Energy = Power × time

Energy consumed by 100W bulb per day = 2 × 100 = 200Wh = 0.2 kWh

Now,

Energy consumed by 110W bulb per day = 4 × 110 × 4 = 1760W = 1.76 kWh

Therefore,

Total energy consumed per day = 0.2 + 1.76 = 1.96 kWh

Hence, Total energy consumed is 1.96 kWh.
