This is because there is a steeper 'electric slope' in place to make the charges slide down steeper slope - faster slide the equation below is used to work out the resistance of a component from measurements of the current flowing through it and the potential difference across its ends can you sketch a circuit diagram of a. Tutorials, tips and advice on gcse physics coursework and exams for students, parents and teachers resistance & length two wires, same diameter, different lengths electrons moving through the short wire only feel resistance for a short time compared to the longer one this means its resistance is less think of the. 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. Gcse cyberphysics factors that affect the resistance of a wire gcse physics resistance & length gcse this means @acuriousmind temperature affects resistanc physics forums how does length affect resistance and resistivity university of the wire archives a factors affecting essay 1216 words. Physics coursework - resistance plan what affects the resistance of a piece of wire there are many variables in this investigation the resistance of the wire could depend on: the voltage from the power pack the voltmeter the ammeter the length of the wire the piece of wire used ie the material it is made. 6 | physics 2007 sample assessment instrument and indicative responses comments hypothesis if the length of a wire is increased then its resistance will increase if its cross-sectional area and temperature remains constant if the cross -sectional area increases then the resistance of a conductor will decrease if its length.
Resistance there is a resistance to the flow of an electric current through most conductors the resistance in a wire increases as: the length of the wire increases the thickness of the wire decreases. Carry out an investigation of the relationship between the length of a metallic conductor (eg nichrome wire) and its resistance introduction “how does the length of a wire affect it's resistance” gather all apparatus put on protective clothing set up apparatus as shown in the diagram set multimeter to the ohm setting. The simplest resistance thermometer configuration uses two wires which is only used when high accuracy is not required as the resistance of the this is not an example of the work written by our professional essay writers any opinions, findings, conclusions or recommendations expressed in this.
Scientific method coursework was introduced to science syllabuses in the early 1990s, attempting to address the concern that some students are not very good at exams whole investigations were introduced to gcse courses which gained a bad reputation because there were many vague criteria that were officiously. Gcse physics resistance & length gcse resistance the physics classroombbc gcse bitesize resistance i am going to give a different explanation why is it that when the length of wire increases(acting as variable resistor) chance them being blocked or whatever) higher resistance i would think would,.
