Q

What is the current flowing through a 52 ohm line with an input of 1,872 watts?

🔍 Key Concepts

• Ohm’s Law relationships between voltage (E), current (I), resistance (R), and power (P) • Power formulas: P = I × E and P = I² × R • How to solve algebraically for current (I) when power and resistance are known

💭 Think About

• Which power formula directly uses only power (P) and resistance (R), so you don’t have to find voltage first? • Once you have a formula that gives I in terms of P and R, what algebraic steps isolate I on one side of the equation? • After you compute the numerical value for current, which of the choices is closest to your calculated value?

✅ Before You Answer

• Make sure you’re using watts for power and ohms for resistance so the formula works directly in SI units. • Double-check your algebra when solving for I so you don’t accidentally take the square or square root in the wrong step. • After calculating I, quickly check using P = I² × R to see if your current value, when squared and multiplied by 52 ohms, comes back close to 1,872 watts.
