🔍 Key Concepts

• Power factor and the relationship between real power, reactive power, and apparent power • How inductive loads and capacitors each affect current and voltage phase angle • The idea of reactive power "oscillating" or "seesawing" between two components in an AC system

💭 Think About

• Think about which type of device causes current to lag or lead the voltage and how a capacitor can counteract that effect. • Ask yourself: in a shipboard AC power system, which component(s) are typically responsible for low power factor that we try to correct? • Consider what actually stores and returns energy in the magnetic field versus in the electric field—what does the capacitor "trade" energy with each cycle?

✅ Before You Answer

• Identify which option(s) are associated with reactive power (kVAR) rather than just real power (kW). • Verify which type of load is commonly cited in textbooks as the main cause of poor power factor that is corrected by adding capacitors. • Check that the device(s) you choose can store and release energy each cycle, not just dissipate it as heat.
