(6\%) Problem 14: Consider a circuit shown in the figure. Ignore the internal resistances of the batteries. Randomized Variables $$\begin{array}{l}{\mathcal{E}}_1=28\mathrm{V}\\ {\mathcal{E}}_2=38\mathrm{V}\\ R_1=9?\\ R_2=10?\\ R_3=6?.\end{array}$$ $$14\%$$ Part (a) Express the current $$I_1$$ going through resistor $$R_1$$ in terms of the currents $$I_2$$ and $$I_3$$ going through resistors $$R_2$$ and $$R_3$$. Use the direction of the currents as specified in the figure. $$I_I={\mathrm{I}}_2+{\mathrm{I}}_3?\text{ Correct! }$$ 14\% Part (b) Write the equation of potential change in loop EBAF in terms of the circuit elements. $$?V_{\mathrm{EBAF}}={?}_1?{\mathrm{I}}_1\left({\mathrm{R}}_1\right)?{\mathrm{I}}_3\left({\mathrm{R}}_3\right)?$$ CorTect! $$14\%$$ Part (c) Write the equation of potential change in loop DCAF in terms of the circuit elements. $$?V_{\mathrm{DCAF}}=?{?}_2+{\mathrm{I}}_2\left({\mathrm{R}}_2\right)?{\mathrm{I}}_3\left({\mathrm{R}}_3\right)?\text{ Correct! }$$ $$?$$ 14\% Part (d) Solve the three equations to get $$I_3$$. $$\begin{array}{l}\text{ Grade Summary }\\ I_3={\mathrm{I}}_2+{\mathrm{I}}_1\\ \text{ Deductions }0\%\\ \text{ Potential }100\%\\ \text{ Submissions }\\ \text{ Attempts remaining: }7\\ \text{ ( 0\% per attempt) }\\ \text{ detailed view }\\ \begin{array}{l}1\\ 2\\ 3\end{array}\\ 0\%\\ 0\%\\ 0\%\end{array}$$ Hints: deduction per hint.
