🔍 Key Concepts

• Ohm’s Law relationships between volts, amps, and watts • Basic power formula for direct current (DC) circuits • How to multiply units to get wattage (V × A = W)

💭 Think About

• Which formula directly relates power (P), voltage (V), and current (I) in a simple circuit? • If voltage is 120 V and current is 30 A, what operation should you perform with these two numbers? • After finding the numerical result, which answer choice is closest to that value?

✅ Before You Answer

• Be sure you’re using the power formula, not Ohm’s Law for resistance. • Check that your final unit is in watts (W), not volts or amperes. • Re‑check the multiplication of 120 × 30 before matching it to the choices.
