Answer 2

Correct Question:

An electric heater is rated 1500 W. How much energy does it use in 10 hours ?

Answer:

Given data:

• Power = 1500 W
• Time taken = 10 hours

To find:

Energy used in 10 hours.

Solution:

We need to find energy consumed so,

as we know that,

Power = Energy consumed/Time taken

So energy consumed will be the product of Power and time taken.

Therefore, energy consumed = Power × Time taken.

Now substitute the known values, we get

Energy consumed = 1500 × 10

= 15000 Wh.
