# LC Circuit **Resonant Charging Choke** (C) in series with **Excitor-array** (E1/E2) forms an **inductor-capacitor circuit** (LC) since the **Excitor-Array** (ER) acts or performs as an capacitor during pulsing operations, as illustrated in Figure (1-2) as to Figure (1-1).
Figure (1-2) [](https://stanslegacy.com/uploads/images/gallery/2023-12/VzsK8hdVflGHQSyd-image-1703011673363.png) | Figure (1-1) [](https://stanslegacy.com/uploads/images/gallery/2023-12/qhtqz9LzDjg4722f-image-1703011664617.png) |
... helping to prevent electron flow within the **pulsing circuit** (AA) of Figure 1-1.
[](https://stanslegacy.com/uploads/images/gallery/2023-12/qhtqz9LzDjg4722f-image-1703011664617.png) The **Inductor** (C) takes on or becomes an **Modulator Inductor** which steps up an oscillation of an given charging frequency with the effective capacitance of an pulse-forming network in order to charge the **voltage zones** (E1/E2) to an higher potential beyond applied voltage input. The **Inductance** (C) and **Capacitance** (ER) properties of the LC circuit is therefore "**tuned**" to resonance at a certain frequency.The Resonant Frequency can be raised or lowered by changing the inductance and/or the capacitance values.
The established **resonant frequency** is, of course, independent of voltage amplitude, as illustrated in Figure (1-3) as to Figure (1-4).
