Gives V=V0sin(1000t+ϕ)

ω=1000s−1,L=100mHC=2μF,R=400Ω

Phase difference θ=tan−1(XL−XCR)

XL=ωL=1000×100×10−3Ω=100Ω

XC=1/ ωC=11000x2×10−6=500Ω

ϕ=tan−1(100−500400)=tan−1(−1)

⇒ϕ=−45∘ Current leads voltage .

(ii) For P.F.=1,R=Z or XL=XC

⇒Ω2=1LC⇒106=1100×10−3×C'

⇒C'=10−5F

Resultant capacitance in parallel.

C'=C2+C1

C2=10−5−.2×10−5=8μF.
