Question
A fuse is marked 10 A and operates normally on a 220 V supply. What is the value of the resistance of the fuse wire?*1 point22.0 Ω13.0 Ω10.8 Ω2.2 Ω
Solution
To find the resistance of the fuse wire, we can use Ohm's Law, which states that Voltage (V) = Current (I) x Resistance (R).
We can rearrange the formula to solve for Resistance: R = V/I
Given in the problem, the Voltage (V) is 220V and the Current (I) is 10A.
Substitute these values into the formula:
R = 220V / 10A = 22.0 Ω
So, the resistance of the fuse wire is 22.0 Ω.
