Pure silver is the best conductor of electricity, then copper, and then aluminum. Silver is the best conductor because it has the least resistance to the flow of electricity. According to Ohm’s Law, current is equal to voltage divided by resistance.
Which materials offer less resistance to the flow of electrical current?
Materials that have low resistance to electric current are called electric conductors. Many metals—including copper, aluminum, and steel—are good conductors of electricity.
What kind of wire has the least resistance?
A short wire has a lower resistance than a long one*. Resistance is directly proportional to the length of the path through which current flows: R ∝ L. This means the longer the wire, the more resistance.
What has the least amount of resistance?
Silver has the lowest resistivity. That means for a given length and diameter of wire it will also have the lowest resistance.
What is a material that does not resist electricity?
Metals are generally very good conductors, meaning they let current flow easily. Materials that do not let current flow easily are called insulators. Most nonmetal materials such as plastic, wood and rubber are insulators.
Are those materials that resist the flow of electric current?
Materials such as plastics have high resistance to electric current. They are called electric insulators. Materials such as metals have low resistance to electric current. They are called electric conductors.
Which material resists the flow of electron?
Circuits depend on conductors: materials that permit the easy and direct flow of electrons through themselves. Some materials such as glass or plastic are poor conductors. In fact, they’re typically used as insulators: materials that resist the flow of electrons through them.
What is the lowest resistance metal?
Silver is the only metal that has the lowest resistance. The electrical resistivity (10.
Which metal offers the least resistance to electric current?
Silver is the best conductor of electricity which means that its electrical resistivity will be the least.
What is the least resistive metal?
Silver is the best conductor because it has the least resistance to the flow of electricity.
Does current flow through least resistance?
However, due to electrons repelling each other the total path of least resistance is in fact to have approximate equal current flowing through each path. … In conclusion, the current is always distributed over all possible paths inversely proportional to their resistance.
Does electricity take path less resistance?
Electricity does take low-resistance paths, including the one of least resistance. But it also takes every other path available to it. You can’t suspend Ohm’s Law and Kirchhoff’s Law by driving 10 ft of copper-clad steel into dirt.
Are metals that generally have the least resistance?
As mentioned metals have low resistance; insulators have high resistance. Metals like nichrome(nickel + chromium) and mercury are much poorer conductors. In general thicker wires offer less resistance. The greater area provides more room for electrons to move through.
Which is not a conductor of electricity?
Insulators oppose electrical current and make poor conductors. Some common conductors are copper, aluminum, gold, and silver. Some common insulators are glass, air, plastic, rubber, and wood.
Is aluminum a conductor?
Aluminum. Aluminum is yet another metal known for its high conductivity of electricity. Though by volume its conductivity is only 60% of copper, by weight, one pound of aluminum has the electrical current-carrying capacity of two pounds of copper. … Aluminum is often used in satellite dishes.
