(10\%) Problem 6: Consider the circuit in the diagram, with sources of emf listed below. Randomized Variables \[ \begin{array}{l} \mathscr{E}_{1}=21 \mathrm{~V} \\ \mathscr{E}_{2}=41 \mathrm{~V} \\ \mathscr{E}_{3}=2.5 \mathrm{~V} \\ \mathscr{Q}_{4}=46 \mathrm{~V} \end{array} \] \( \triangle 33 \% \) Part (a) Find \( I_{1} \) in amps. \[ I_{l}=\mid \] Hints: deduction per hint. Hints remaining: 3 Feedback: 10 deduction per feedback. \( \triangle 33 \% \) Part (b) Find \( I_{2} \) in amps.
