🔍 Key Concepts

• Effect of shorted turns in an AC coil (what happens to the number of effective turns) • Relationship between number of turns, inductance, and current in a coil • How I²R heating and magnetic flux change when part of the winding is short-circuited

💭 Think About

• If several turns become shorted together, does the coil behave like it has more turns, fewer turns, or the same number of turns? How does that affect current draw? • What happens to power dissipation and temperature in a winding when current increases but the resistance path is partly bypassed? • Would shorted turns make the coil easier or harder to magnetize, and what does that mean for heating or burnout?

✅ Before You Answer

• Check how coil resistance changes when turns are shorted: does the current path get longer or shorter? • Consider whether inductive reactance increases or decreases when effective turns are lost. • Verify whether increased current would cause the coil temperature to rise or fall, and whether that could be sudden enough to damage it.
