Question 1 of 27070

The apparent power supplied to a motor is six kilovolt amps at 120 volts. What is the impedance of the motor?

🔍 Key Concepts

• Apparent power (S) in volt-amps and how it relates to voltage (V) and current (I) • Relationship between impedance (Z), voltage, and current in an AC circuit • Unit conversions between kilo-volt-amps (kVA) and volt-amps (VA)

💭 Think About

• First, convert the given apparent power in kVA to VA, then solve for current using the basic power relationship • Once you know the current, use Ohm’s Law for AC circuits to relate voltage, current, and impedance • Compare your calculated impedance value with the choices and watch for misplaced decimal points

✅ Before You Answer

• Confirm you correctly converted kVA to VA before doing any calculations • Verify you used the correct formula relating S, V, and I: $S = V \times I$ for apparent power in a single-phase circuit • Double-check your final impedance calculation using Z = V / I and ensure the units are ohms (Ω)
