<The best electrical conductor we use here on earth is
Gold.....second is SILVER...... and the latter is the COPPER....the cheapest
of all!..........GOLD being the best.....it has almost no Voltage drop! or
almost zero electrical resistance.>
Most of what you said is true. However as a point of clarification your
list of the best conductors is a little out of order. This is the correct
order with the specific resistance in ohms of each type of wire being 1 foot
long: Silver (9.9), Copper (10.4), Gold (14.7). As you can see gole is not
the conductor with the lowest electrical resistance. The reason that it is
preferred in car applications is that it resists corrosion and tarnishing.
This trait of gold is important in high current applications because in cars
current flows on the outside diameter of the wire. Other than that your
statement is correct.
