What are resistor networks made out of?

Question

I am trying to do a school project and I can't seem to find this information. I know it is obviously some type of plastic coating and a metal but I need to know what kind.

Answer 2

A resistor is a two-terminal electrical or electronic component that resists an electric current by producing a voltage drop between its terminals in accordance with Ohm's law: The electrical resistance is equal to the voltage drop across the resistor divided by the current through the resistor. Resistors are used as part of electrical networks and electronic circuits.
Identifying resistors
Most axial resistors use a pattern of colored stripes to indicate resistance. SMT ones follow a numerical pattern. Cases are usually brown, blue, or green, though other colors are occasionally found like dark red or dark gray.
One can use a multimeter to test the values of a resistor

Resistor standards
MIL-R-11
MIL-R-39008
MIL-R-39017
BS 1852
EIA-RS-279
There are other MIL-R- standards
silver 10%
gold 5%
red 2%
brown 1%
green 0.5%

Answer 3

Abstract. The critical properties of a random resistor network are investigated, using an infinitesimal Migdal-Kadanoff renormalization group transformation, for cases where the non-zero conductors have a probability distribution h(g) which behaves as g- alpha , 0
