Chapter 17, Problem 10P

For the network in Fig. 17.47:

a. Find the total impedance ZT and the admittance YT.

b. Find the current I1, I2, an I3.

c. Verify Kirchhoff’s current law by showing that ${\text{I}}_{\text{s}}{\text{- I}}_{\text{1}}{\text{+ I}}_{\text{2}}{\text{+ I}}_{\text{3}}$

d. Find the power factor of the network, and indicate whether it is leading or lagging.
