what is ment by resonance in an AC circuit
Answers
Answer:
Resonance in an AC circuit that state of circuit in which the inductive reactance of the circuit is equal to its capacitive reactance
Explanation:
Resonant circuits have the variety of applications for example in tuning mechanism of radio or the TV set. The antenna of radio accepts signals from many broadcasting stations. The signals picked up in antenna acts as source in the tuning circuit of radio. the circuit can be driven at many frequencies .But to hear one particular radio station we tune the radio. In tuning we vary the capacitance of a capacitor in the tuning circuit such that resonant frequency of the circuit becomes nearly equal to the frequency of the radio signal received.
Answer:
The point at which the inductive reactance and capacitive reactance become equal for an AC circuit is called resonance.
Explanation:
Consider an AC circuit is connected with an inductor, capacitor, and resistor in a series manner. A capacitor is used to store electric energy and in an inductor, the electric energy is stored in the form of a magnetic field. Both the inductor and capacitor provide a reactance to the circuit. If the reactance is in the form of a magnetic field then it is called inductive reactance and if the reactance is in the form of an electric field it is called capacitive reactance.
The resonance condition is said to occur when both the inductive and capacitive reactances are equal to each other. At the resonance condition, the amplitude of the current in the circuit will be the maximum.
