Question 432Electricity/Electronics - Assistant Engineer70% to pass
In actual applications, electrical connections associated with 'R1, R2 and R3' of the transmitter to 'R1, R2, and R3' of the indicators shown in figure "C" of the illustration are made by what means? Illustration EL-0092

AI Explanation
The correct answer is C) slip rings and brushes.
Slip rings and brushes are used to make the electrical connections between the transmitter and the indicators in the illustration, as this allows for the continuous, uninterrupted transmission of the signal while the components are rotating. This is a common method for connecting electrical circuits on rotating machinery, as it avoids the need for fixed, rigid connections that could be damaged by the rotation.
The other answer choices are not correct because: A) soldered contacts would not withstand the rotation, B) spliced and taped connections would not be robust enough, and D) solderless crimp-on connectors would not provide a reliable connection for a rotating system.
