Comparison of physical terms and their geographical significance in circuit theory
Terms Geographical significance Current Probability of each element flowing through a geographic unit in the pattern of spatial protection and development Resistance The resistance to development of the spatial unit; the geographical unit with a tendency toward protection is assigned a high resistance value Voltage The probability that the spatial element leaves a node and successfully reaches a specified node is also the probability that two nodes can be connected through the axis Effective resistance Resistance distance of different paths between nodes Ground Endpoint of the spatial development axis
