Question

An electrical appliance is used at $1000kVA,220V$. If the appliance is operated for $2h$, calculate the energy consumed by the appliance in:
$kWh$

Answer 1

Step 1 Given data:
$$\begin{gathered} P=1000kVA=1000kW \\ t=2h \\ V=220V \end{gathered}$$

Step 2 Formula used:
Energy consumed in $kWh$ is
$E=P\times t$
Where, $E$ is the Energy consumed, $P$ is the Power, $t$ is the time.

Step 3 Calculating the energy consumed by the appliance in $kWh$:
We know that,
Energy consumed in $kWh$ is given by $E=P\times t$
$E=1000\times 2=2000kWh.$
Therefore, the energy consumed by the appliance in $kWh$ is $2000kWh.$
