Each network shown below has several of its branch currents or voltages specified numerically. Several other branch currents or voltages are labeled as unknowns.

Find all labeled unknown branch currents and voltages. **Note that the elements in the networks are drawn as non-specific boxes, indicating that they can each be a source or a resistor.**

For questions that ask for more than one value, enter them as a Python list. So if a question asks for v1 and v2, where v1 = 2 V and v2 = 7 V, enter

`[2,7]`

.##Network A

Enter the values of v_1 and v_2 [in V] as a Python list.

[v_1, v_2]=

[v_1, v_2]=

##Network B

Enter the values of i_1, i_2, and i_3 [in mA] as a Python list.

[i_1, i_2, i_3]=

[i_1, i_2, i_3]=

##Network C

Enter the values of v_1, v_2, and v_3 [in V] as a Python list.

[v_1, v_2, v_3]=

[v_1, v_2, v_3]=

##Network D

Enter the values of i_1, i_2, and i_3 [in mA] as a Python list.

[i_1, i_2, i_3]=

[i_1, i_2, i_3]=
