A plastic spatula is not a conductor, as electricity does not transfer through plastic. A metal spatula is a conductor, since the metal used in kitchenware is often steel (stainless is the most popular), and steel is a conductor. While a better conductor would be copper, aluminum, silver, or gold, steel does conduct electricity.
copper,a reddish-orange metal,is the best low-cost electrical conductor available
because metal is a good conductor of energy (there are a lot of free electrons in a metal) and this will cause the metal to absorb and radiate more energy combined with the increased surface area of the heat sink
The liquid commonly used in a thermometer is mercury or COLOURED ALCOHOL.
Conductors- Most types of metal. Copper and Aluminium are used these days. Silver is a very good conductor but it is expensive. Insulators- rubber, plastic and wood are good insulators in the solid state.
Copper Metal is used because it is good conductor of electricity
Copper is the most commonly used conductor material in wiring, steel is also used but is much firmer and harder to bend.
Copper is the most commonly used due to reasonably high conductivity, moderate cost, and the fact that its oxide is conductive and easily sloughs off.
Copper
aluminum
The most commonly used conductor of electricity is copper. For larger size service conductors the most commonly used conductor for electricity is aluminum. Aluminum service conductors are used to keep the overall cost of the project lower and are lighter to work with than copper wire.
Copper is used for wiring!
copper
mercury
wood
The most common metal is uaually iron for gates
the first commonly metal used was wood
