For an LCR sereis circuit with an angular freequency omega .
In a series LCR circuit, operated with an ac of angular frequency omega , the total impedance is
In an LCR series circuit the current is
In R-L-C series circuit, we have same current at angular frequencies omega_(1) and omega_(2) . The resonant frequency of circuit is
An inductance L and capacitance C and resistance R are connected in series across an AC source of angular frequency omega . If omega^(2)gt (1)/(LC) then
There is a series LCR circuit connected to an AC source of angular frequency 3xx10^(5) rad/s . It is found that circuit is in resonance mode at this frequency and voltages across resistor and inductor are found to be 80 V and 60 V respectively . Calculate L and C . Resistance used in the circuit is 160 Omega .
What is the power factor of an LCR circuit connected to an AC source of angular frequency (1)/(sqrt(LC)) ?
Resistor of resistance R and capacitor of capacitance C are connected in series to an AC source of angular frequency omega . Rms current in the circuit is I. When frequency of the source is changed to one - third of initial value keeping the voltage same then current is found to be halved. Find the ratio of reactance of capacitor to that with resistance at the original frequency omega .
