Atorque will cause them to align to the same position

Breceive a lower voltage depending on the turns ratio

Cring at the receiving station until the turning stops

Dreceive a higher voltage depending on the turns ratio

AI Explanation

The correct answer is A) torque will cause them to align to the same position. When the coil 'R1-R2-R3' on the transmitter is turned 30 degrees clockwise, it will create a magnetic field that will induce a corresponding change in the coils 'R1-R2-R3' on the receivers (indicators). Due to the principle of electromagnetic induction, the receiving coils will experience a torque that will cause them to align to the same 30-degree clockwise position as the transmitter coil. The other options are incorrect because: B) the voltage change would depend on the turns ratio, not the coil position; C) the coils would not ring, they would simply align; and D) the voltage change would depend on the turns ratio, not the coil position.
