Question 1 Report

Which of the following apparatus will require the smallest fuse rating for its protection?

60W, 240V

60W, 40V

40W, 12V

40W, 5V

Answer Details

I = $\frac{P}{V}$ = $\frac{60}{240}$ = 0.25A

I = $\frac{P}{V}$ = $\frac{60}{40}$ = 1.5A

I = $\frac{P}{V}$ = $\frac{40}{12}$ = 3.3A

I = $\frac{P}{V}$ = $\frac{40}{5}$ = 8A
