Chapter 8, Problem 4RQ

Refer to the circuit shown in Figure 6-22. The circuit has an applied voltage of 24 V and the resistors have values as follows:

$\begin{array}{l}{\text{R}}_{\text{1}}\text{= 1 k }\Omega \hfill \\ {\text{R}}_{\text{2}}\text{= 300 }\Omega \hfill \\ {\text{R}}_{\text{3}}\text{= 750 }\Omega \hfill \\ {\text{R}}_{\text{4}}\text{= 1 k }\Omega \hfill \end{array}$

An ammeter and a voltmeter indicate the following values:

$\begin{array}{l}{\text{I}}_{\text{T}}\text{= 42}\text{.5 mA}\hfill \\ {\text{I}}_{\text{1}}\text{= 24 mA}\hfill \\ {\text{E}}_{\text{1}}\text{= 24 V}\hfill \\ {\text{I}}_{\text{2}}\text{ = 18}\text{.5 mA}\hfill \\ {\text{E}}_{\text{2}}\text{= 5}\text{.5 V}\hfill \\ {\text{I}}_{\text{3}}\text{ = 0 A}\hfill \\ {\text{E}}_{\text{3}}\text{= 18}\text{.5 V}\hfill \\ {\text{I}}_{\text{4}}\text{ = 18}\text{.5 mA}\hfill \\ {\text{E}}_{\text{4}}\text{= 18}\text{.5 V}\hfill \end{array}$
