In some professional electrical tests, series resonance and parallel resonance are definitely used, and these must meet a series of conditions during use.

Firstly, it is necessary to understand the products that need to be analyzed in the experiment, as different products generally use completely different voltages during use. This must be noted during the use process, during the experiment, it is necessary to strictly follow the corresponding formulas to effectively minimize the factors that are unfavorable to the experiment. Therefore, professionals will strictly control this point throughout the entire experiment process.  

Secondly, in the process of testing the series resonant device, because basically all voltages need to be adjusted in different currents, and there will be a certain proportion. Then, the required data will gradually increase, and the obtained data will be integrated and analyzed. This can also help oneself obtain some more professional data. However, it should be noted that in the experiment, it is not enough to simply conduct a set of experiments to quickly obtain data, as the information obtained is generally not particularly accurate. So the number of experiments must be as much as possible, so that more accurate data can be obtained during the process of viewing and analyzing the data. This can effectively avoid many troubles in the later use process. Secondly, the conditions required for different experiments are generally completely different, so these issues must be clarified in advance, fully prepared, and then tested.
