Question

an electric oven is rated 200w.how much unit of energy does it consumes in 5 hours​

Answer 1

Answer:

Explanation:

Power rating of the electric oven = 200 Watts

Time for which the electric oven is On = 5 hours = 5 × 60 × 60

Time for which the electric oven is On (t) = 18000 seconds

Power is defined as the rate at which the energy is consumed.

Hence, the formula for power is:

Power = \frac{Energy}{t}Power=tEnergy​

Energy consumed = Power × t

Energy consumed = 200 × 18000

Energy consumed = 3600000 Joules

Hence, the energy consumed by the electric oven in 5 hours is 3600000 Joules.

Answer 2

Given:

• An electric oven is rated 200 watt.
• Time = 5 hours

Need to find:

• Unit of energy it consumes in 5 hours.

Answer:

• it consumes 40 joules in 5 hours.

Step by step explanation:

Energy = Power/time

=> 200/5

=> 40 joules

Hence, it consumes 40 joules in 5 hours.
