Answer 2

Given,

The electrical power of an electric geyser = 2500 Watts

The total duration of use = 1 hour 30 mins

To find,

The total electrical energy consumed in kWh.

Solution,

We can simply solve this numerical problem by using the following process:

Mathematically,

Power (P)= Energy consumed (E) ÷ Time (T)

=> Energy consumed (E) = Power (P) x Time (T)

Now,

Total units of energy consumed by the electric geyser

= Power (P) x Time (T)

= 2500 W x 1.5 hours

{Since 60 minutes = 1 hour}

= 3750 Wh

= 3.75 kWh = 3.75 electrical units

(Since 1 kWh = 1 electrical unit)

Hence, the total electrical energy consumed is equal to 3.75 electrical units.
