What is the basic "control action" of a magnetic amplifier dependent upon?
AI Explanation
The correct answer is B) changes in inductance.
The basic "control action" of a magnetic amplifier is dependent upon changes in inductance. Magnetic amplifiers operate by utilizing the change in inductance of a reactor or transformer winding when a control current is applied. This change in inductance then modulates the main power signal, allowing the magnetic amplifier to act as an amplifier or switch. The other options, changes in resistance, capacitance, and conductance, are not the primary mechanisms by which a magnetic amplifier operates.
