The electrical energy consumed by a toaster is 0.033 Kwh.

Explanation:

The power utilized by the toaster is 400 W.

$\text { The power utilized by the toaster is } 400 \mathrm{W} \text { in kilo-watts is } (400)/(1000)=0.4 \mathrm{Kw}$

The toaster is operated for 5 Minutes.

$\text { The toaster is operated for } 5 \text { Minutes in hours is } (5)/(60)=0.083 \text { hours. (One minute is } 60 \text { seconds) }$

We know that,

$\text {power}=\frac{\text {energy}}{\text {time}}$

Substitute the values in the above formula to obtain electrical energy,

$0.4=\frac{\text { energy }}{0.083}$

Electrical energy = 0.4 × 0.083

Electrical energy is 0.033 Kwh.
