Question

what is the difference between current amplitude and maximum current in case of an LCR circuit connected to an AC source of changing frequency? Does the current amplitude change because of the changing frequency?​

Answer 1

Answer:

In a series LCR circuit connected to an ac source of variable frequency and voltage v=vmsinωt, draw a plot showing the  variation of current (I) with angular frequency (ω) for two different values of resistance R1andR2(R1>R2), Write the condition under which the phenomenon of resonance occurs. For which value of the resistance out of the two curves a sharper resonance is produced? Define Q-factor of the circuit and give its significance 

Hope it helps;)
