🔍 Key Concepts

• Relationship between power (kW), voltage (V), and current (A) in DC circuits • How to convert kilowatts to watts • Checking if an answer is reasonable in size for the given power and voltage

💭 Think About

• What is the basic formula that links power, voltage, and current in a DC circuit? Rearrange that formula to solve for current. • First change 10 kW into watts, then plug into your formula with 125 V and solve for current. • After you compute the current, which answer choice is closest to your calculated value?

✅ Before You Answer

• Be sure you converted kilowatts to watts correctly before calculating. • Verify you used the correct formula for DC power, not AC three-phase power. • Check that your final current value is not unrealistically small or huge for a 10 kW motor at 125 V.
