###Part 1

Use the node method to find i in the figure below:

Enter the value of i in A.

###Part 2

As always, for the question below, do not use underscores, so enter R_1 as R1, R_2 as R2, R_3 as R3, R_4 as R4, V_S as VS and I_S as IS.

Write a node equation at node e_1 and solve it for e_1, developing an in terms of R1, R2, R3, R4, Vs and Is. e_1=

Write a node equation at node e_2 and solve it for e_2, developing an in terms of R1, R2, R3, R4, Vs and Is.
e_2=
