When conducting circuit experiments, we may encounter words like series resonance (also known as variable frequency resonance). Do we understand the specific meaning of words like this? Now let’s briefly introduce the specific meaning of series resonance.
Firstly, such series resonance phenomenon usually occurs in a circuit containing both capacitors and inductors. This phenomenon occurs when he sets conditions for you. In learning about circuit related knowledge, we can understand that the phenomena of capacitance impedance and inductance are specific to different dynamic components.
When conducting circuit experiments where all three components of the circuit, inductance and resistance, are present, when the capacitance is equal to the inductance, the current and voltage phases in the circuit will be equal. And at this point, the circuit becomes a pure resistance circuit. The pure resistance circuit mentioned here does not mean that the circuit only contains resistors. This component represents a symbolic meaning, not just a literal meaning. Simply put, when this phenomenon occurs, it becomes what we call a series resonance phenomenon.
There are many characteristics in this circuit phenomenon, one of which is that when this phenomenon occurs, the impedance in the circuit can be determined by its formula, which represents the total impedance of the circuit. At this time, it also represents that the current in the circuit has reached its maximum value. This feature can provide a lot of design inspiration for many circuit designers.
Because if we want to create a circuit that can maximize the current in the circuit when certain conditions are met, then we can adopt this phenomenon to design the circuit, which achieves the designer’s ultimate goal of using existing circuit knowledge to greatly reduce the time required for design.
