A bread toaster uses a current of \(4 \mathrm{~A}\) when plugged in a 240 volts line it takes 1 minute to toast slices of bread. What is the energy consumed by the toaster?
A. \(1.60 \mathrm{x}\) \(10^{2} \mathrm{~J} \) B. \(3.60 \times 10^{2} \mathrm{~J} \) C. \(1.60 \times 10^{2} \mathrm{~J} \) D. \(5.76 \times 10^{2}\)
Correct Answer: D
Explanation
Energy \(=\) IVT Where \(\mathrm{I}=4 \mathrm{~A}\) and \(\mathrm{V}=240\), \(\mathrm{t}=1\) mins \(=60\) seconds \(t=4 \times 240 \times 60=57600=5.6 \times 10^{4}\)
