What is the impedance of a ceramic capacitor?

In circuits with resistors, inductors, and capacitors, the blocking effect on the current in the circuit is called impedance. Impedance is a physical quantity that represents the performance of a component or the electrical performance of a segment of a circuit. The effective value or peak of the voltage across a passive circuit in an AC circuit. The ratio of (UM) to the current rms or peak (IM) through the circuit is called impedance and is expressed in z in ohms (Ω). In the case of a certain U, the large z is small, and the impedance has a limiting effect on the current.

In both direct current and alternating current, the resistance is detrimental to both currents. As the value of the ceramic capacitor increases or the AC power increases, the blocking effect of the capacitor on the alternating current is small. This hindrance can be understood as "resistance", but it is not equivalent to the resistor. This is a kind of reactance, reactance and resistance. The unit is the same, collectively called "impedance." To be precise, "impedance" should have three parts, except for these two, which are "inductive". Inductive reactance is the blocking effect of the inductor on the current. Contrary to the capacitor, the inductor has no obstructive effect on the direct current, and has an obstructive effect on the alternating current. The unit of the inductive reactance and the unit of the capacitive reactance and the resistance are all ohms.

The concept of impedance is not only in the circuit. From the mechanical point of view, in the vibration system, the impedance is also represented by Z. It is a complex number and a phasor, composed of resistance and resistance. Resistance is the consumption of energy, and resistance is the preservation of energy. In the vibration system, the resistance generated by the mass is the mass resistance, and the resistance generated by the stiffness is the stiffness resistance.
