Question

Obtain a relation for impedance in lcr circuit and ots phase analysis

Answer 1

Answer:

Let, V=V

0

sinωt

Where, X

L

= Inductive reactant.

X

C

= Capacitive reactant

and i= Current in circuit

Impedance Z is

Z=

R

2

+(X

L

−X

C

)

2

From Phasor diagram,

i=

Z

V

0

sin(ωt−ϕ)

where ϕ= Phase difference.

ϕ=tan

−1

(

R

X

L

−X

C

)

solution

Answer 2
