Chapter 8, Problem 4PP

Refer to the circuit shown in Figure 8-25 to solve the following problems.

Find the unknown values in the circuit if the total current is 0.8 A and the resistors have the following values:

$\begin{array}{l}{\text{R}}_1=1.5\text{k}\Omega {\text{ R}}_2=910\Omega {\text{ R}}_3=2\text{k}\Omega {\text{ R}}_4=3.6\Omega \\ {\text{E}}_{\text{T}}\_\_\_\_\_{\text{ E}}_1\_\_\_\_\_{\text{ E}}_{\text{2}}\_\_\_\_\_{\text{ E}}_{\text{3}}\_\_\_\_\_{\text{ E}}_{\text{4}}\_\_\_\_\_\\ {\text{R}}_{\text{T}}\_\_\_\_\_{\text{ I}}_{\text{1}}\_\_\_\_\_{\text{ I}}_{\text{2}}\_\_\_\_\_{\text{ I}}_3\_\_\_\_\_{\text{ I}}_{\text{4}}\_\_\_\_\_\end{array}$
