I understand that in a Frequency Response experiment dealing with an RLC circuit, the graph of Current against Frequency is supposed to be symmetrical about the resonant frequency theoretically. However, experimentally it is not the case. Could anyone explain why this happens? |

For every RLC circuit there is an total impedence in the circuit which will lead to loss of current in the form of heat due to resistance . the total impedence is equal to square root of sum of squares of resistance in resistor and total reactance in the circuit(i.e. difference between the reactance of capacitor and inductor) hence in experiment the is always an change in value of current which will be always less then that of theoritical value |
