Participation reward: 2 Wealth. Reward for correct answer: 9 wealth. When two transformers with different turns ratios operate in parallel, circulating currents are generated, which cause voltage drops within both transformers, resulting in a decrease in the voltage at their output terminals. A. All increase B. All decrease C. Those with a larger transformation ratio increase, while those with a smaller ratio decrease D. Those with a smaller transformation ratio increase, while those with a larger ratio decrease 【Haichuan Thanksgiving】--Production Division 【Production and Management Division】is seeking moderators and technical discussants to join us
When two transformers with different turns ratios operate in parallel, circulating currents are generated, which cause voltage drops within both transformers, resulting in a voltage difference at their output terminals (C). A. Both increase B. Both decrease C. Those with a larger transformation ratio increase, while those with a smaller transformation ratio decrease D. Those with a smaller transformation ratio increase, while those with a larger transformation ratio decrease

A. Both increase B. Both decrease C. Those with a larger transformation ratio increase, while those with a smaller transformation ratio decrease D. Those with a smaller transformation ratio increase, while those with a larger transformation ratio decrease
C: Increase for a large turns ratio, decrease for a small turns ratio
