Resistive Network -Ch. 3 Learning objectives of this lecture z Solve circuits using the node voltage method z Solve circuits using the mesh current method Node z A node is a point at which two or more circuit elements are joined together z One of the nodes can be selected as reference node R 1 i S R 3 R Node a Node b Node c Node Voltage z Node voltage is the voltage between a node and the reference node. z The node has the positive reference polarity and the reference has the negative polarity z The voltage across an element is the difference of the two node voltages that the element is connected to. v ab =v a -v b is the voltage across the element that connects node a and b . The positive reference polarity is at node a . R 1 i S R 3 R 2 Node a Node b Node c v a v b v c =0 v ab + Branch current formulation in nodal analysis +− v ab
