What is the electrical resistance of a penny?
The electrical resistance of a penny can vary based on its composition and condition, but a typical copper penny (post-1982) has a resistance of about 1 to 2 ohms. This value can change due to factors like oxidation, surface condition, and temperature. Generally, the resistance is low due to copper's excellent conductivity.
What is the current in a copper wire that has a resistance of 2 ohms and is connected to a 9-volt electrical source?
Current equals Voltage divided by Resistance. 9/2=4.5 amps.
What is a material that allows current to easily flow?
A conductor is a material that allows current to easily flow.
Is there any copper inside an arc welder?
Like any mechanical tool, machine or similar engineering equipment, an arc welder will have lots of different materials inside it. An arc welder is an electrical machine and any electrical machine must have wiring inside it. Most electrical wiring will be made of Copper. So yes, there is likely to be some Copper inside an arc welder.
What type of current is produced in a generator?
In order to generate an electric current, a magnet is moved near copper, usually copper wires. Because of the magnetic field affecting the copper, an electric current is formed due to the electrons moving in the copper.
Do copper carry current?
Yes, copper is a good electrical conductor.
What is the oxidation state of copper in the compound CuCl2?
+2 oxidation state for the Copper. -1 for the Chloride
Is gold and copper good conductors of an electrical current?
Yes.
Is oxidation of copper exothermic or endothermic?
Copper oxidation is endothermic.
What is the difference between copper and polystyrene as an insulator?
Copper is a conductor of electricity, meaning it allows the flow of electrical current, while polystyrene is an insulator, meaning it inhibits the flow of electrical current. Copper is a metal with high electrical conductivity, whereas polystyrene is a non-metallic, synthetic polymer with low electrical conductivity.
What is a conductive material that controls electrical fields and reduces RF interference and signal loss in cables?
Copper mesh.
Will copper carry a electric current?
Yes, very easily. Copper is an excellent electrical conductor.
What is a substance that dissolves in solution to conduct an electrical current?
In a normal battery; Copper and Zinc.
Metalic copper formula?
Depends on it's oxidation state. It can be Cu2+ for copper (II) or it can be Cu+ for copper (I)
What is the oxidation state of cupric ion in copper tartar-ate?
The oxidation state of the cupric ion in copper tartarate is +2. Copper (II) ion, or cupric ion, has an oxidation state of +2 due to the loss of 2 electrons. In the case of copper tartarate, the ligand (tartarate) does not affect the oxidation state of the central copper ion.
Copper oxidation number?
It depends on the compound. +1 and +2 are the more common ones (as in Cu2I2 and CuI2 respectively). In elemental form, its oxidation number is zero.
Difference between cucl and cu2cl2?
CuCl is copper (I) chloride, where copper has a +1 oxidation state. Cu2Cl2 is copper (II) chloride, where copper has a +2 oxidation state. The difference lies in the oxidation state of copper present in the compounds.
