Question

An alternating L-C-R circuit is shown in figure, then match the column : (Here symbols have their usual meaning)

Column I	Column II
(A) If  ωL1 - R1 and ωL2 - 1/ωC2 = R2	(p) I =  I1 and I2 are in same phase
(A) If  ωL1 -  1/ωC1 = R1 and  1/ωC2 - ωL2 = R2	(q) I = I1 + I2 ; (I, I1 , I2 rms value of currents)
(C) If capacitor C1 and inductor L2 are removed from circuit and  ωL1 -  R1 , 1/ωC2 = R2	(r) Magnitude of phase difference between I1 and I2 is π/2
(D) If capacitors C1 and C2 are both removed from circuit and ωL2 -  R2,ωL1 = R1	(s) I =  ; (I, I1 , I2 rms value of currents)
	(t) I1 is lagging and I2 is leading from source voltage

Answer 1

(B)  -r,s,t ; (C)  - r,s,t ; (D) - p, q

(B) Phase difference
