The electrical energy consumed by a toaster is 0.033 Kwh.
Explanation:
The power utilized by the toaster is 400 W.
[tex]\text { The power utilized by the toaster is } 400 \mathrm{W} \text { in kilo-watts is } \frac{400}{1000}=0.4 \mathrm{Kw}[/tex]
The toaster is operated for 5 Minutes.
[tex]\text { The toaster is operated for } 5 \text { Minutes in hours is } \frac{5}{60}=0.083 \text { hours. (One minute is } 60 \text { seconds) }[/tex]
We know that,
[tex]\text {power}=\frac{\text {energy}}{\text {time}}[/tex]
Substitute the values in the above formula to obtain electrical energy,
[tex]0.4=\frac{\text { energy }}{0.083}[/tex]
Electrical energy = 0.4 × 0.083
Electrical energy is 0.033 Kwh.
