An oscillating kennel is a closed electrical circuit that consists of a capacitor and an inductor. In this case, the resonance frequency of the oscillating circuit is related to the value of the capacitance of the capacitor and the inductance of the coil. This phenomenon is used to isolate certain frequencies of electrical vibrations. Therefore, to change the oscillation frequency of the oscillating circuit, a variable capacitor or a coil with variable inductance is included in the oscillating circuit.
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
