What are two types of electric current?
Current electricity is a constant flow of electrons. There are two kinds of current electricity: direct current (DC) and alternating current (AC). With direct current, electrons move in one direction. Batteries produce direct current.
Is gold good conductor?
Gold is used as a contact metal in the electronics industry as it is a good conductor of both electricity and heat. Gold wire Gold is ductile: it can be drawn out into the thinnest wire. © AMNH / Craig Chesek. Gold conducts heat and electricity.
Is a good conductor of electricity?
Silver Conductivity “Silver is the best conductor of electricity because it contains a higher number of movable atoms (free electrons). For a material to be a good conductor, the electricity passed through it must be able to move the electrons; the more free electrons in a metal, the greater its conductivity.
What are three physical properties of gold?

What are the properties and uses of gold?
Properties, occurrences, and uses. Gold is one of the densest of all metals. It is a good conductor of heat and electricity. It is also soft and the most malleable and ductile of the elements; an ounce (28 grams) can be beaten out to 187 square feet (about 17 square metres) in extremely thin sheets called gold leaf.
