🔍 Key Concepts

• Power factor in an AC system (what it physically represents) • Relationship between voltage, current, and phase angle in an AC circuit • What actually causes the phase shift between voltage and current

💭 Think About

• Ask yourself: Does the machine by itself set the power factor, or does something external to the generator decide it? • Which of these choices can change the phase angle between voltage and current in the connected circuit? • Which option is most directly tied to whether the load is inductive, capacitive, or resistive?

✅ Before You Answer

• Identify which choice is related to the nature of the load (inductive/capacitive/resistive). • Eliminate options that mainly affect frequency or magnitude of voltage, not the phase relationship. • Confirm which factor actually determines the angle between current and voltage, since that angle defines power factor.
