# Problem 1-4: Elements, Nodes, Loops and Branches

How many elements / nodes / loops / branches does the following circuit have?

Solution
8 elements
6 nodes, as shown:

# Problem 1-3: Using Power and Conductance

Determine the resistance of the resistor, $I$ and $V$.

# Problem 1-1: Power of Elements

Find the power of each element. Which one is supplying power and which one is absorbing it?

Solution

a)  Passive sign convention, $P = V \times I = -8 W < 0$ supplying power.
