Answer» 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»

ANSWER:

Let, V=V

sinωt

Where, X

= Inductive reactant.

= Capacitive reactant

and i= Current in circuit

Impedance Z is

+(X

−X

)

From PHASOR diagram,

sin(ωt−ϕ)

where ϕ= PHASE difference.

ϕ=tan

−1

(

−X

)
