Deck 9: Phasors and Impedances

Question 1

the circuit shown below, let

Answer 1

Question 2

Find V in polar notation.

Answer 2

clear all;
V1-P2Rd (11, 110)
V1p=R2P (V1)
V2=P2Rd (17, -75 )
V2p=R2P (V2)
V=V1+V2
Vp-R2P (V)

Question 3

phasors to express the following equation as a single cosine.

Answer 3

clear all;
V1=P2Rd (45, -120-90+180 )
V1p-R2P (V1)
V2=P2Rd (65, 150-90)
V2p=R2P (V2)
V=V1+V2
Vp=R2P (V)
