Power of Electrical Circuit: Practice Problem & Solution

Solution Explained:

To solve this problem, we apply the core principles of Power of Electrical Circuit. Understanding the underlying formula is key to arriving at the correct answer below:

The resistance is given by $R = \frac{V^2}{P}$. Substituting the values, $R = \frac{(220)^2}{60} = \frac{48400}{60} \approx 806.67\Omega$, which rounds to $807\Omega$.
