Feasibility Analysis of the Application of “Equivalent Circuit” Principle in Table Tennis

: This paper introduces the idea of "equivalent circuit" principle in physics, and uses the methods of theoretical analysis, empirical analysis and literature reference to discuss the feasibility of its application in table tennis theoretically, and makes further empirical analysis on the operability of "equivalent circuit" principle in the practical application process through multiple examples of three major projects of technology, tactics and psychology. The results show that the principle of "equivalent circuit" in physics is almost the same as that of multi ball training, tactical training and psychological training in table tennis technology, and their "equivalent principle" is interlinked. Therefore, table tennis teaching and training can also draw lessons from and use the idea of "equivalent principle", which is used for the intellectual development of table tennis researchers, coaches and high-level athletes The improvement of generalization ability and the development of innovative thinking are of practical significance.
