Question on: JAMB Physics - 1992
Which of the following apparatus will require the smallest fuse rating for its protection?
A
60W, 240V
B
60W, 40V
C
40W, 12V
D
40W, 5V
Ask EduPadi AI for a detailed answer
Correct Option: A
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
