Recommended: Factors Affecting Resistance Of Wires

Relationship Between the Resistance and the Length of a Wire Aim: To find the relationship between the resistance of the wire and

the length of the wire

Background

Factors:

i. Temperature : If the wire is heated up the atoms in the wire will

start to vibrate because of their

increase in energy. This causes more collisions between the electrons

and the atoms as

the atoms are moving into the path of the electrons. This increase in

collisions means that

there will be an increase in resistance.

ii. Material : The type of material will affect the amount of free

electrons which are able to flow through the wire. The number of

electrons depends on the amount of electrons in the outer energy

shell of the atoms , so if there are more or larger atoms then there

must be more electrons

available. Also if the atoms in the material are closely packed then

the electrons will have more frequent collisions and the resistance

will increase.

iii. Wire length : If the length of the wire is increased then the

resistance will also increase as the

electrons will have a longer distance to travel and so more collisions

will occur. Due to this

the length increase should be proportional to the resistance increase.

iv. Wire width : If the wires width is increased the resistance will

decrease. Due to this increased space between the atoms there should

be less collisions.

The factor I am going to change is the length of the wire. To measure

and record the findings for this factor would be simple and the

    An atom, by definition, is the smallest part of any substance. The atom has three main components that make it up: protons, neutrons, and electrons. The protons and neutrons are within the nucleus in the center of the atom. The electrons revolve around the nucleus in many orbitals. These orbitals consist of many different shapes, including circular, spiral, and many others. Protons are positively charged and electrons are negatively charged. Protons and electrons both have charge of equal magnitude (i.e. 1.602x10-19 coulombs). Neutrons have a neutral charge, and they, along with protons, are the majority of mass in an atom. Electron mass, though, is negligible. When an atom has a neutral charge, it is stable.

    There are three main parts of an atom the electrons, protons and the neutrons. Each part has charge. It is rather positive, negative, or neutral. An electron always has a negative charge. Protons always have negative charges. Then finally the neutron is a neutral charge or a charge of zero. If the charge of the whole atom it zero that means there are an equal number of positive and negative pieces. An electron can be found anywhere around the nucleus, and the protons and neutrons are in the nucleus. You can not pin point were the electrons are but the area that it can be in is called a shell.

  • The Complexity of the Copper Atom

    To understand the complexity of the copper atom, there must first be an understanding of the basic structure of a general atom. Atoms are considered to be the simplest of matter; impossible to dice into smaller pieces. There are, however, subatomic particles that are the building blocks of the uncountable atoms that make up the earth: protons, neutrons, and electrons. The positively charged particles (protons) and neutrally charged particles (neutrons) make up the nucleus, the electrons surround the nucleus in a cloud. The configuration and number of electrons are crucial in making up and distinguishing elements.

  • Ways of Transmitting Heat: Conduction, Convection and Radiation

    1201 Words  | 3 Pages

    Conduction, convection and radiation are the three methods through which heat can be transferred from one place to another. The (www.hyperphysics.com) first method is the conduction through which heat can be transferred from one object to another object. This process is defined as the heat is transmitted from one to another by the interaction of the atoms and the molecules. The atoms and the molecules of the body are physically attached to each other and one part of the body is at higher temperature to the other part or the body, the heat begins to transfer. A simple experiment through which conduction can be understood easily is as follows. First of all, take a metallic rod of any length. Hold the rod in the hand or at any stand made up of the insulator so that the heat does not transfer to the stand. Heat up the one end of the rod with the help of the spirit lamp. After sometime, touch the other end of the end, the other end of the becomes heated too and the temperature of the other end of the rod has also increased. Although only one end of the rod is heated with the spirit lamp, but the other end of the rod has also been heated. This is represents that the heat has been transferred from one end of the rod to the other end of the rod without heating it from the other end. So, the transformation of the heat is taking place. This process is called the conduction. Conduction is a process which is lead by the free electrons. As the conduction happens occurs only in the metallic materials, the reason for it is that the metals has the free electrons and they can move freely from one part of the body to another part of the body. These electrons are not bounded by the nucleus so, they can move easily. And when the temperature of the ...

  • The Ultimate Nature of Matter

    2017 Words  | 5 Pages

    The theory of quantum mechanics has divided the atom into a number of fundamental sub-atomic particles. Although the physicist has shown that the atom is not a solid indivisible object, he has not been able to find a particle which does possess those qualities. Talk of particles, though, is misleading because the word suggests a material object. This is not the intention for the use of the word in quantum physics. Quantum particles are, instead, representations of the actions and reactions of forces at the sub-atomic level. In fact, physicists are less concerned with the search for a material particle underlying all physical objects and more interested in explaining how nature works. Quantum theory is the means that enables the physicist to express those explanations in a scientific way.

  • What I have Learned in Chemistry, Grade 10

    To start off, learning the Bohr-Rutherford diagrams in grade nine was a very big confusion for me. I had never fully understood how many shells should go around the nucleus nor did I know how to do the many calculations. As I progressed into grade ten, the teachings became easier. The review shows an example such as in the the bohr diagram, a nucleus is in the center, which is a little circle, and following that there are shells surrounding it containing electrons. Each ring can only hold a certain amount of electrons, and so the first shell around the nucleus can hold a maximum of 2 electrons, the next shell is able to hold a maximum of 8 electro...
