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.
