Question

An amplidyne can give which of the following characteristics?

(a) Constant current

(b) Constant voltage

(c) Constant current as well as constant voltage

(d) Constant current, constant voltage and constant power

I had been asked this question during an internship interview.

My enquiry is from Stability of Nonlinear System topic in portion Nonlinear Systems of Control Systems

Answer 1

The correct option is (d) Constant current, constant voltage and constant power

The explanation is: An amplidyne is the device so constructed so as can give constant current, voltage and power and it is the important device as single device can achieve all these features.
