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 of wire: Length Potential difference Tension Temperature Diameter

Sectional Crisis Leading to the civil war there were a plethora of things that impacted the unity of the nation as a whole. Two major events that contributed to this were the Compromise of 1850 and the Kansas Nebraska Act. Both of these events changed the relationship of the nation in many ways. The Compromise of 1850 was a compromise that stated California would be admitted as a free state‚ the slave auction would end in Washington D.C‚ settlers of Mexico and Utah would decide whether

Discuss the Pros and Cons of Cross-sectional and Longitudinal approaches to the study of development The study of development is that of changes in physical‚ cognitive‚ social and emotional capabilities over time. The study is usually carried out on infants and children as their changes are faster and more dramatic than adults. These time based studies reveal that the data collected shows the abilities of subjects and the ages they appear. The data is collected through interviews‚ observations

two division‚ north and south‚ were located in the same country but were very different from each other. The North and the South made it very clear that they live different lifestyles. Their terrain was different along with their tariffs. These sectional differences in way of life led to the American Civil War. The daily lifestyle of a southern was very different from the lifestyle of a northerner. In the south many were farmers. They grew cash crops such as cotton and tobacco. These crops were

Physics GCSE coursework: Resistance of wire Aim: To investigate if the length of wire affects its resistance. Prediction (Hypothesis): I predict that the longer the wire the higher the resistance‚ and the shorter the wire the lower the resistance. Knowledge: Resistance is that property of electric components that turn electric energy into heat in opposing the passing of an electric current.It can be beneficial‚ as in electric heaters‚ or a pest‚ as in light bulbs‚ where the heat

How does the length of a wire affect its resistance? Introduction: This first report in Physics will show the investigation of how the length of a wire affects its resistance. For starters I will go through the main definitions‚ to get a better knowledge of what is going to happen. However I will plan it out first to show each step of how I started‚ and then go into detail about the results and what the investigation on a whole has showed me. I shall then conclude my findings and present them with

Length of a Wire Affects Its Resistance In my physics coursework I am going to investigate the effect of the length of a wire on its resistance. Resistance is the measure of how easy it is for current to flow through a wire. Current is the rate of flow of charge through a conductor‚ and it is measured in amps using an ammeter. To help me plan my investigation I have completed a preliminary experiment in which I investigated the effect of the thickness of a wire on its resistance‚ using three constantan

Child mortality in Madhya Pradesh : a cross sectional analysis The millennium development goals (MDGs) have been widely accepted as a framework for improving health and welfare worldwide. Child mortality is one of the most crucial and avoidable global health concerns. In many low income countries‚ 10-20% of children die before reaching 5 years of age . The child mortality in MDG (to reduce the under 5 mortality rate by two thirds between 1990 and 2015) is formulated as a national average.(UN- child

Resistance in a Conductor: The electrical resistance of an electrical conductor is the opposition to the passage of an electric current through that conductor. Electrical resistance shares some conceptual parallels with the mechanical notion of friction. The SI unit of electrical resistance is the ohm (Ω).An object of uniform cross section has a resistance proportional to its resistivity and length and inversely proportional to its cross-sectional area. All materials show some resistance‚ except

Factors Affecting The Resistance Of Wire Aim: To investigate the factors that affect the resistance in a conductor. The main factors that affect the resistance in a conductor are: · Length · Temperature · Cross sectional area · Material · Magnetism The factor that we are going to change is the cross sectional area. Hypothesis: I think that the higher the cross sectional area‚ the lower the resistance in the conductor will be. This is because the Resistance in a metal conductor happens
