Question

Calculate the energy consumed in kWh by
1500 W electric geyser in 3 hrs in a day

Answer 1

Answer:

4.5 kWh

Explanation:

1500x3=4500 Whr

4500/1000=4.5kWhr

Answer 2

1. The capacity to do work is called Energy$(E)$. Its SI unit is Joule$(J)$.
2. The rate of work done is called Power$(P)$. Its SI unit is Watt$(W)$.
3. We know that, energy can be calculated using the formula, $E=P\times t$, where $t$ is time in seconds.

Step 1: Given data

Power consumed by electric geyser, $P=1500W$

Time taken by electric geyser, $t=3hrs$

Energy consumed by the electric geyser$=?$

Step 2: Calculating the energy consume in $kWh$

$P=1500W=\frac{1500}{1000}=1.5kW$

$E=P\times t=1.5\times 3=4.5\ kWh$

Hence, $4.5\ kWh$ amount of energy is consumed by the electric geyser.
