Type: MCQ-numerical-Easy-Class 12
A⁵⁻A fuse wire can withstand a maximum power of 1 W in circuit. The resistance of the fuse wire is:
A
0.02 Ω
B
0.2 Ω
C
0.4 Ω
D
0.04 Ω
Correct Answer
Option D
Detailed Explanation
Using the formula P = I²R, where P is power and I is current, we can solve for R: R = P/I² = 1/(5²) = 0.04 Ω.
