Question

an electric heater I rated 2000 watt how much energy does it use in 5 hours

Answer 1

Answer:

hope you will understand that

Answer 2

Given:

Rated Power = 2000 W

Time = 5 hrs

To Find:

Energy Consumption

Solution:

We know that,

Power (P) = 2000 W = 2000/1000 kW = 2 kW

Time (t) = 5 hours

P = $\frac{E}{t}$

By rearranging, we get

E = P × t = 2 × 5 kWh = 10 kWh = 10 units

Hence, the electric heater rated 2000 watt uses 10 kWh of energy in 5 hours of time.
