Resonance is the phenomenon in the electrical circuit, where the output of the circuit is maximum at one particular frequency. There is always a certain amount of uncertainty in the exact frequency of the output circuit. It is usually taken for granted that we can know this value with some precision, but there are situations where we can't be sure.
The resonance of a series RLC circuit occurs when the inductive and capacitive reactance are equal in magnitude but cancel each other because they are 180 degrees apart in phase. The sharp minimum in the frequency of the performance is 0.05 cycles per second, which is 4 times lower than its ideal value of 1 cycle per second.
The phenomenon of resonance in an ideal circuit is one of the most fundamental challenges in applied physics. When current flows through a perfect parallel circuit, no matter how much current is flowing, it will remain quiescent at all times. This is because any current flowing through the path of an electric field will produce an equal magnetic field at that point in space.
