🔍 Key Concepts

• Understand what a saturable-core reactor does on its own • Know how a magnetic amplifier controls power using a control (bias) winding • Think about how DC vs AC or rectification affects control of an AC load

💭 Think About

• Ask yourself: What extra component is needed so that a small control signal can regulate a larger AC load current without moving parts? • Which option would allow the device to turn the AC in the controlled circuit into something more easily varied by changing core saturation? • Which of these choices is typically associated with power control circuits, not just protection or minor tuning?

✅ Before You Answer

• Verify which option is commonly paired with magnetic amplifiers in power-control applications (power electronics context). • Check whether a plain saturable-core reactor already has a bias winding; if yes, what must be added to become a magnetic amplifier? • Eliminate options that are more about protection or reactive compensation rather than core saturation control of load current.
