🔍 Key Concepts

• Power factor as the ratio of real power (kW) to apparent power (kVA) • How load characteristics (resistive, inductive, capacitive) affect phase angle between voltage and current • What a single AC generator actually controls versus what the connected load determines

💭 Think About

• Which of these options directly changes the phase relationship between voltage and current in the system? • Does changing the generator’s speed, frequency, or rated voltage by itself make the current more or less out of phase with the voltage, if the load stays the same? • If you swap out the types of equipment connected to the bus (motors, heaters, transformers), what happens to power factor even though the generator itself is unchanged?

✅ Before You Answer

• Be clear on the definition of power factor: PF = kW / kVA = cos(φ) • Identify which choice is tied to the nature of the load (inductive / resistive / capacitive) rather than the generator’s nameplate data • Confirm which item would still determine power factor even if you connected the same generator to a completely different set of loads
