🔍 Key Concepts

• Use Ohm's Law for AC/DC circuits: V = I × R (voltage = current × resistance/impedance) • Understand that impedance in ohms works like resistance in this type of calculation • Pay attention to units: amperes (A), ohms (Ω), and volts (V)

💭 Think About

• What formula directly links voltage (V), current (I), and impedance/resistance (R or Z)? • If the current is 10 A and the impedance is 11 Ω, what do you get when you multiply these values? • Once you calculate the voltage, which of the multiple-choice options matches your result most closely?

✅ Before You Answer

• Confirm you are using V = I × R (or V = I × Z) and not mixing up with power formulas like P = V × I • Re-check your multiplication of 10 amperes × 11 ohms • Verify that your final result is expressed in volts and matches exactly one of the listed choices
