Exercise 6: Answers

Model Answer

From The Diagram

From Node b we get:

From Node d we get:

It is clear that we must solve V_c, in order to complete Voltage definitions at all nodes. V_c will be found by applying KCL at Node c and solving resulting equations Follows:

We can group like terms to get the following equation:

Substitute values into previous equations you get:


Thus now we can calculate Current through as follows:

Thus the effective current through is in opposite direction to Just as we expected!
