Lec23 | Chapter 20 AC Circuits | Class 12 Physics Sindh Board| Working & Construction of Resonanace in Tuning Circuit of Radio | AQ Academy Definition: When a specific frequency is applied to an LCR circuit, it causes the reactance of the inductor (XL) and the reactance of the capacitor (Xc) to be equal. This is when the circuit is in a state of resonance. This only happens at one specific frequency, which is called the resonant frequency. Video Summary: This video discusses resonance in the tuning circuit of radio receivers: Function of Tuning Circuits: Tuning circuits in radios receive frequencies, achieving a state to catch specific frequencies, known as the resonance state [00:19]. Selective Reception: Resonance enables the selective reception of desired radio frequencies, rejecting others [01:01]. For example, a circuit might be tuned to receive 88 MHz while rejecting other frequencies [02:06]. Principle Behind Selective Reception: This involves the cancellation of inductive and capacitive reactance within the LC circuit [03:02]. When these reactances are equal, maximum current flows at a specific frequency, which the radio receiver then picks up [03:36]. Tuning Circuits as LC Circuits: Tuning circuits, also known as LC circuits (inductor and capacitor), help create resonance [04:46]. Adjusting capacitance and inductance tunes the circuits to resonate at specific frequencies [05:35]. Benefits of Tuning Circuits: They allow radios to receive signals from a specific station without interference from others [06:43]. Importance of Radio Broadcasting: Radio broadcasting has been a powerful medium for reaching a wide audience, impacting societies, educating, entertaining, connecting people, and preserving culture [07:42].
