The resistance of the coil is 12. 97 Ω

<h3>How to determine the length</h3>

The formula for resistance is given as;

R = V/I

Note that resistance, R is measured in Ohms and represented with the symbol ( Ω)

Where;

Substitute the values into the formula

R = 120/ 9. 25

R = 12. 97 Ω

The resistance, R is 12. 97 Ω

Hence, the resistance of the coil is 12. 97 Ω
