Document Summary
The values for currents and voltages depend on the underlying circuit topology (network structure. Current takes the path of least resistance within a circuit. A node is a point where various elements have a common connection. Lines on a circuit diagram represent an ideal (zero resistance) connection. The path through an element is a branch. Any components connected between the same two nodes are said to be in parallel. The path is a sequence of connected elements: node branch node. A path is a series connection of components if all nodes in the path have no other connection. All series components have the same current. The sum of currents entering a node is zero. The sum of the currents flowing into a node must equal the sum of the currents flowing out. States that charge cannot build up at a point. Applies for any number of branches feeding a node. Current out: negative (cid:498)what flows in must flow out(cid:499)
