Copper wires
Not much thicker than a human hair, these copper wires
are twisted together and woven into a tight bundle. One
of the main uses for these wires is to shield a thicker copper wire that transmits a signal to a
television. As the signal carries pictures and sounds in the form of electrical currents, the wires
wrapped around it prevent interference from other electrical sources nearby.070-071_Copper_DPS.indd 70 02/12/16 6:52 pm
