Chapter 7, Problem 7P

For the network in Fig. 7.70.

a. Does

$I_s=I_5=I_6?\text{Explain}$

b. If

$\begin{array}{l}{I}_{\text{s}}=10\text{A and}\\ I_1=4\text{A},\text{find }{l}_2.\end{array}$

c. Does

$I_1+I_2=I_3+I_4?\text{Explain}\text{.}$

d. If

$\begin{array}{l}V2=\text{8V and}\\ E=14\text{V},\text{find}{V}_{3.}\end{array}$

e. If

$\begin{array}{l}\text{R}1=4\Omega \text{,}\\ \text{R2=2}\Omega \text{,}\\ \text{R3=4}\Omega \text{, and}\\ \text{R4=6}\Omega \text{, what is }{\text{R}}_{\text{T}}?\end{array}$

f. If all the resistors of the configuration are 20 $\Omega$ what is the source current if the applied voltage is 20 V?

g. using the values of part (f), find the power delivered by the battery and the power absorbed by the total resistance R_T
