Node voltage node voltage method is based on the independent circuit variables as circuit analysis methods. Choose a node in the circuit as a reference node, and 38 datasheet and the remaining nodes and 38 price and the voltage between the reference point called the node that corresponds to the voltage. Polarity of the voltage reference node are nodes corresponding to positive polarity side of the reference node for the negative side. With the curse of the circuit nodes, the node voltage method is (n-1) independent node node voltage solution variables, and 38 suppliers and independent of the node list with KCL node voltage with the expression of the branch current equation. 39. What is diffusion? What is the drift movement? diffusion: the material is always the direction from high concentration to low concentration of local movemen...
