Question 365Electricity/Electronics - QMED70% to pass
Basically, a magnetic amplifier is a saturable-core reactor with the addition of what additional feature?
AI Explanation
The correct answer is A) a rectifier in the load circuit.
A magnetic amplifier is a type of saturable-core reactor, which is a device that uses the saturation of a magnetic core to control the flow of electrical current. The addition of a rectifier in the load circuit is what distinguishes a magnetic amplifier from a basic saturable-core reactor.
The rectifier in the load circuit allows the magnetic amplifier to control the magnitude and direction of the output current, making it a more versatile and useful device compared to a simple saturable-core reactor. The other options, such as AC to the bias winding (B), eddy current protectors (C), or variable capacitance (D), are not the defining feature that distinguishes a magnetic amplifier from a saturable-core reactor.
