Answer

123.76 volts Explanation 1. Identify the formula Use the power formula: **P = \frac{V^2}{R}** where P is power, V is voltage, and R is resistance. 2. Rearrange the formula to solve for Voltage Rearrange to find V: **V = \sqrt{P \times R}**. 3. Substitute values and calculate Substitute P = 1801 watts and R = 8.5 ohms into the formula: V = \sqrt{1801 \times 8.5}.
