🔍 Key Concepts

• Operation of a saturable reactor – how the control winding affects the core’s saturation and the main (load) winding • Difference between loss mechanisms (hysteresis, eddy currents, I²R losses) and control effectiveness or gain • What gain means in this context: change in output versus change in control current

💭 Think About

• Which choice directly limits how much the output can change in response to a small change in control current, rather than just wasting power? • In a saturable reactor, is the main limitation on gain due to core losses, copper losses, or the magnetic coupling between control and load windings? • Think about how the control winding influences the effective inductance of the load winding—what property of that control circuit could reduce how strong that influence is?

✅ Before You Answer

• Distinguish between losses (which reduce efficiency) and factors that reduce control sensitivity (gain) • Ask: does this option describe something that heats the core/conductor, or something that impedes changes in control current? • Verify which choice is directly associated with the control winding circuit, not just the power winding or core material in general
