🔍 Key Concepts

• AC contactor coil behavior when turns are shorted • Relationship between number of turns, current, and coil heating in an electromagnetic coil • Effect of short-circuited turns on coil impedance (resistance + inductive reactance)

💭 Think About

• If some of the coil turns are shorted together, what happens to the effective number of turns in use and the coil’s impedance? • When impedance decreases in an AC coil supplied with the same voltage, what happens to the current and the heating effect? • Which choice best matches what would happen to a coil that is drawing abnormally high current due to reduced effective turns?

✅ Before You Answer

• Compare each option to what would happen if current increases sharply in the coil. • Ask yourself: would reduced turns tend to lower or raise the coil’s temperature, and why? • Eliminate any options that assume less current or lower temperature if you conclude the impedance is reduced and current rises.
