🔍 Key Concepts

• Ohm’s Law and Power Law relationships in DC circuits • Formula for electric power using voltage (V) and current (I) • Unit conversion and meaning of a watt

💭 Think About

• Which formula directly relates power, voltage, and current without needing resistance? • If power equals voltage times current, what is the numerical result when you multiply the given values? • After calculating, which choice is closest to your result and has the correct order of magnitude (tens, hundreds, or thousands of watts)?

✅ Before You Answer

• Be sure you’re using P = V × I and not mixing in unnecessary formulas. • Re‑check the multiplication of 120 × 20 carefully. • Confirm that your final unit is watts (W) and that it matches one of the answer choices.
