Resistance of a Wire
Task To investigate how the resistance of a wire is affected by the length of the wire. Theory What is resistance? Resistance is a force which opposes the flow of an electric current around a circuit so that energy is required to push the charged particles around the circuit. The circuit itself can resist the flow of particles if the wires are either very thin or very long. e.g. The filament across an electric light

Physics Coursework Theory - Resistance of a Wire
Theory behind my experiment Thickness (cross sectional area of the wire), length, and temperature all have some effect on the amount of resistance created in a wire. Another factor is the conductivity of the material we are using. Some metals are just more electrically conductive than others. As long as I use the same type of metal for each wire, my experiment will remain fair. Cross Sectional Area The thicker the wire, the less resistant

Resistance of a Piece of Wire
Planning In this piece of coursework, I am going to investigate what affects the resistance of a piece of wire. Wire is made up of atoms. Electric current is a flow of electrons, and it is these electrons that collide with the nucleus of the atoms. Every time this happens, it causes resistance. The build up of friction is what produces the heat. There are many variables that could affect the resistance of the piece

Resistance of a Wire
Theory What is resistance? Electricity is conducted through a conductor, in this case wire, by means of free electrons. The number of free electrons depends on the material and more free electrons means a better conductor, i.e. it has less resistance. For example, gold has more free electrons than iron and, as a result, it is a better conductor. The free electrons are given energy and as a result move and collide with neighbouring free

What Factors Affect the Resistance of a Wire?
What Factors Affect the Resistance of a Wire? Planning Background Electricity flows around a circuit in a current. A current is the flow of electrons. Currents are measured in amps. Voltage is the force which pushes electricity through a wire. Voltage comes from a cell or a socket. Voltage is measured in volts. Electrical resistance is a measure of the degree to which a body opposes the passage of an electric current. (en.wikipedia.org/wiki/Resistance(electricity). Resistance is

Resistance to Oppression
Currently in the United States various forms of oppression afflict people of color everyday. The National Association for the Advancement of Colored People (NAACP) has been trying to amend this problem since the early 20th century. Their organization has defined oppression as confining minorities to the lower limit and outer edge in political, social, and economic aspects of life (Martin). The first strategy of resistance their organization should try to incorporate is education. Lawrence Blum,

Resistance Basic Guide
A basic guide to resistance. Electron Flow Model Everything is made of very small particles called atoms. Each atom has a heavy positively charged nucleus and is surrounded by a cloud of light, negatively charged, electrons. In metals, the outer most electron of each atom is weakly attracted to the positive nucleus and can escape from the atom and wander around between the atoms. [Note 1] So, in metals, we have all these millions and
