3. In the Figure below, ?1 = 16 V, ?2 = 5.0 V, ?3 = 7.0 V, R1 = 2.0 ?, R2 = 3.0 ?, and R3 = 5.0 ?. Find electric currents i1, i2 , and i3. (Hint: use the junction a and the two loops to find the currents). (30 points)
Use the following equations:
Junction rule: i_in = i_out Loop rule: ? Voltages = 0
