Question on: JAMB Physics - 1999
A 3000W electric cooker is to be used on a 200V mains circuit. Which of the fuses below can be used safely with the cooker?
A
2A
B
5A
C
10A
D
20A
Ask EduPadi AI for a detailed answer
Correct Option: C
The maximum current drawn by the cooker is given by;
I = P/V
∴ I = 3000/200
I = 15A
Thus the most suitable fuse to be used is a 10A fuse
