AI Thread Summary
To calculate resistance in a multi-material cable consisting of copper, tin, and lead wires, use the resistivity formula for each material. If the wires are connected in parallel, determine the combined resistance accordingly. The total voltage at the other end of the cable will depend on the current flowing through the circuit. Insulation of the wires is also a consideration for accurate calculations. Understanding these principles is essential for effective electrical engineering.

Hi, if I have 3 naded wires copper, Tin and Lead wrapped into one cable and I run 12v through it how do I work out the amount of resistance I get and the total voltage at the other end?

You mean insulated wires?

You work out the resistance of each wire (using the resistivity formula) and then the combined resistance of the wires in parallel if they are connected in parallel.

The voltage out depends on the current, of course.
 

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
