Question

An electric ovan is rated 1600 W. How much energy ( In kWh) does it use in 8 hours?

​

Answer 1

Solution:-

Given➝

Power (P) = 1600 W,

time (t) = 8 hrs

To find➝

Energy (E)

Formula➝

E = P × t

Calculation➝

From formula,

E = 1600 × 8 = 12800 Wh

E = 12.8 kWh

Ans: The energy consumed by the ovan in 8 hrs is 12.8 kWh.
