🔍 Key Concepts

• Review the power triangle shown in figure B and how each side is labeled: apparent, reactive, and true power. • Recall that active (real) power is the portion that actually does useful work like turning a motor shaft or heating an element. • Understand the common electrical power units: kW, kVA, and kvar, and which one is tied to power factor.

💭 Think About

• On the triangle in figure B, which side represents the power that is converted into useful mechanical work by the motor? • Which unit is associated with the horizontal leg (often called true or real power) rather than the hypotenuse or vertical leg? • How is power factor defined in terms of the quantities on the triangle, and which choice in the list looks like that definition?

✅ Before You Answer

• Identify which label on the triangle corresponds to true/real/active power. • Match the triangle’s labels to the answer choices’ units: kW, kVA, kvar, and any ratio between them. • Verify which quantity is used when calculating power factor = ( ? ) / ( ? ) so you don’t mix up active power with apparent or reactive power.
