Answer
10.58 $\Omega$
Work Step by Step
The formula that connects Resistance (R), Voltage (V) and Current (I) is:
R=$\frac{V}{I}$
The data contained in the question highlights that V=115 V
The value of I was found in Part (a) to be 10.87 A
By substituting both these values in the formula above, R is found to be 10.58 $\Omega$
Therefore, R=10.58 $\Omega$
