Click here:point_up_2:to get an answer to your question :writing_hand:in series lcr circuit at resonance the impedance is equal to the ohmic resistanceAssertion (A): In series LCR circuit resonance can take place. Reason (R): Resonance takes place iff inductive reactance and capacitive reactances are equal with phase difference 180?.

In the adjoining circuit calculate the inductive reactance and the capacitive reactance. What should be the source frequency so that the two reactance become equal in magnitude? What would then be the impedance (in ohms) of the circuit?

 

A coil has resistance 30 ohm and inductive reactance 20 Ohm at 50 Hz frequency. If an ac source of 200 volt 100 Hz is connected across the coil the current in the coil will be

 

In a series LCR circuit L = 10 mH C =1 ?F and R = 3 ?. It is connected to an AC voltage source. The inductive reactance of the circuit at a frequency 25 % less than resonant frequency is

Explain inductive reactance. show grapically variation of inductive reactance with frequency of applied alternative voltage. b)at AC Voltage B=Vosinwt is applied across pure inductor find the expression of current . show that current lags behind voltage by 90 degree

 

The inductive reactance of a coil is 1000 ?. If its self inductance and frequency both are increased two times then inductive reactance will be

 

A coil has resistance 30ohm and inductive reactance 20ohm at 50H z frequency. If an ac source of 200volt 100H z is connected across the coil the current in the coil will be
