Q

What would be the voltage across a 50-ohm dummy load dissipating 1,200 watts?

🔍 Key Concepts

• Relationship between power (P), voltage (V), and resistance (R) in a purely resistive circuit • Using the correct power formula: $P = \frac{V^2}{R}$ and how to solve it for V • What a dummy load is (a resistor that converts electrical power into heat, with no reactance)

💭 Think About

• Which formula directly links power, voltage, and resistance without involving current? • If $P = \frac{V^2}{R}$ , how can you rearrange this to solve for V in terms of P and R? • After calculating the voltage, which of the multiple-choice answers is numerically closest to your result?

✅ Before You Answer

• Be sure you use ohms (Ω) for resistance, watts (W) for power, and you end up with volts (V) for voltage. • Carefully compute $V = \sqrt{P \times R}$ and double-check the square root step. • Verify that your final voltage value, when put back into $P = \frac{V^2}{R}$ , gives you about 1,200 W.
