Document Summary
Where is some constant representing the resistivity" of the material . All resistors in series have the same current magnitude. The total resistance of a circuit of resistors in series is the sum of the resistances - R = r+ r+ + r. Two elements connected at a node pair are in parallel. Elements in parallel always have the same voltageacross their terminals. A parallel relationship is between 2 resistors, if there is another resistor some of the voltage is dissipated. Parallel circuits split current between their elements. But sometimes we have semiconductors like silicon which can have a range of resistivities depending on the impurities. We model conduction bands with physical space to represent resistance in a conductor, semiconductor and an insulator. Take a triangle and connect each side at one node. We can indicate that resistors are in parallel with. If you have two voltage sources in parallel, v= v.
