Electrical Engineering XYZ MCQs
In single phase rotary converter the number of slip rings will be:
- Six
- Two
- Three
- Four
Correct answer: 2. Two
Explanation: In a single-phase rotary converter, which is essentially a type of electrical machine used to convert single-phase alternating current (AC) into direct current (DC), there are typically two slip rings. This configuration arises because the rotary converter is fundamentally similar to a single-phase motor. It uses one of the slip rings for the input AC connection and the other for providing the excitation to the field winding. Unlike three-phase systems that might use more slip rings depending on their design and application, the single-phase setup generally requires only two to complete its function efficiently and effectively.
