Q

An electric heating element supplied with 120 volts draws 15 amps. How much power will be consumed?

🔍 Key Concepts

• Power formula for DC circuits (relationship between volts, amps, and watts) • Difference between volts (V), amperes (A), and watts (W) • Basic multiplication of electrical quantities: P = V × I

💭 Think About

• What is the standard formula that connects power (in watts), voltage (in volts), and current (in amps) in a simple electric circuit? • If the element uses 120 volts and draws 15 amps, how would you combine those two numbers using that formula? • After you calculate the result, which of the answer choices is closest to your computed value?

✅ Before You Answer

• Be sure you’re using power (P) = voltage (V) × current (I), not a formula involving resistance (ohms). • Double-check your multiplication of 120 × 15 before matching it to an answer choice. • Confirm that your final unit is in watts (W) to match the question and answer options.
