Resistivity of Copper Wire of Different Lengths In this report I will be writing about the experiment I will conduct on copper wire of different lengths. The dependent variable I will be measuring is the resistance of the Copper wire. To do this experiment‚ one needs to obtain measurements with a high degree of accuracy‚ taking care of the equipment they use and measuring each value to a certain degree of accuracy for all results. The problem with measuring the resistivity of Copper wire is due to the properties

did was to find the resistance of a piece if wire. The piece of wire is my dependent variable throughout the investigation. I changed the length of the wire in order to measure the resistance of each length. Plan In this investigation‚ a simple circuit will be set up to read the voltage and current when the length of the wire changes. The length will range from 10cm-80cm with intervals of 10cm. The length of the wire will be changed by moving the crocodile clip across the wire and checking the measurements

Investigating the resistance of a wire. Planning For this investigation there are a number of variables that can be chosen to change or keep the same‚ these are: · Length of the wire. · Diameter of the wire. · Type of the wire. · Temperature of the wire. Scientific explanation. All electrical conductors resist current through them to some extent. This is resistance and this affects the size of the current flow. The main dependence of resistance are: § It’s Length. § It’s Thickness

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 it is. This is because there are more electrons

Investigation: how the resistance in a circuit varies with the length‚ thickness and type of wire Introduction A current is a flow of negative electrons around a circuit or electrical pathway. This is measured in how many electrons per second or the charge they are carrying go round the circuit (amps or amperes) Voltage or Potential Difference measures how much energy individual electrons have to use up as they go around a circuit. (Volts) Components in a circuit have a Resistance value which will

effect of Length on the overall resistance of a circuit. Research question: How does the length of the conductive putty affect the over all resistance of a circuit? This experiment will be discussing how the length of the conductive putty wire affects the overall resistance of a circuit. The variables for this experiment are being used for a number of reasons‚ however one of the main reasons behind choosing this experiment is investing how length of an object is affected be the resistance.

How does Length affect resistance? Coursework Aim To find out how the length of a wire can affect resistance. Factors affecting resistance  Temperature  Length of wire  Thickness  Type 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. Resistance is measured in ohms. The symbol for an ohm is Ω Here is the rule for working out the
