2. ConductorsA conductor has many free electrons so is good at transferringelectrical current- -- - -- ------ - -- -- Low ResistanceHigh Resistance Good ConductorBad Conductor Conductance is the opposite of resistance It is measured in Mhos (ohm backwards) 3. Different types of conductorsMaterial UsedAluminumCopperHigh conductivity 60%Easily soldered conductivityHeavier & more of copperexpensive thanaluminum Cheap &Copper used in house lighter thanwiring copper 1mm2, 1.5mm2 Galvanized Iron (GI) 4mm2 , 6mm2 Heavier than aluminum Lowest Used in conductivity overheadlines 4.
