🔍 Key Concepts

• Paralleling AC generators – what conditions must be met before closing the breaker (voltage, frequency, phase) • Synchronizing lamps method – how lamp brightness changes as the phase relationship between two AC sources changes • What it means physically when all synchronizing lamps are dark at the same time

💭 Think About

• Think about what causes the lamps to get bright and dim when two generators are slightly out of phase with each other. • If the two generators had exactly the same voltage, frequency, and phase, what would the potential difference across each lamp be? • How would the behavior of the lamps differ if the generators were running at the same speed but still out of phase vs. truly synchronized in phase angle?

✅ Before You Answer

• Verify what zero phase difference between two AC voltages implies for current through the lamps. • Check whether speed alone (same RPM) guarantees that the lamps are dark, or whether something else must also match. • Confirm that a synchroscope is not being used in this method, so any choice referring to it is suspect.
