Why are some materials good conductors?

Answer	In conductors, some electrons can move freely between atoms, creating current flow. This usually happens when the outer electrons are not tightly bound. WHY IT MATTERS: It’s the basic reason aircraft power can be distributed through wiring. AIRCRAFT EXAMPLE: Copper conductors allow easy electron flow in a 737 electrical harness. MEMORY AID: Conductor = electrons can “walk around.” EASA TIP: If the question mentions “free electrons,” the correct concept is conductivity.
