Designing an experiment to investigate factors affecting the voltage of an electrochemical cell michellecho mee ji h2ruby background information. Potentialdifference resistance= current in my investigation we were finding out how resistance is affected by the legnth of a wire for this we needed potential difference and current when electrons move through a resistor they collide nwith stationery particles in the resistor.

Introduction the purpose of this investigation is to expose the factors responsible for affecting the resistance of a wire in an electrical circuit many factors will have to be investigated prior to experimentation. 2) series connections of resistance if you connect resistance in series, it's resistance value will become larger 3) short-circuiting if you place a short-circuit like a piece of wire parallel to the resistance load, the resistance will be by-passed, therefore the resistance value becomes zero. 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. Investigating the effect of length on resistance is common but some students may wish to investigate the effect of the thickness of wire in either case, different wires should be made of the same material.
Investigate the factors affecting the internal resistances of cells finding the internal resistant of a cell is a common and standard sixth form physics practical however, it could be extended to look at how the internal resistance of a cell varies under certain conditions. My aim is to find the factors, which affect the resistance of a wire or a conductor these factors are: (a) material from which wire is made, (b) length of wire, and (c) thickness of wire i will choose to look at three different materials: copper, constantan and nichrome and find out which one offers more resistance than others. Aim: to try and find out the different resistances of a wire at different lengths and thickness resistance (r)= voltage (v) current (c) equipment power pack- so that we can safely control the voltage we put into the wires.
Dhruv nandakumar 2/18/16 resistance in a wire lab 1 p urpose to investigate the relationship between the resistance of a wire and its length and the relationship of the resistance of a wire and its cross sectional area 2 a pparatus kanthal a-1 wires of different gauges (26,29,32 awg) connecting wires voltmeter meter stick. 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. 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. Physics investigation resistance of wire essay while the free essays can give you inspiration for writing, they cannot be used 'as is' because they will not meet your assignment's requirements.
The aim of this experiment is to investigate the ways in which thickness (or rather the cross sectional area) affects the resistance of a wire, how it affects it, and why this happens. Physics lab report adnaan thakur resistance of wire aim - to investigate the change in resistance as a result of changing diameter of a resistance wire. Factors affecting electrical conduction through the use of independent variables such as the material of the conductor, the thickness of the conductor, the variation in temperature of a conductor and presence of impurities within a conductor. This year, the concept of resistance will be extended by looking at the factors that affect resistance in a resistor, namely: the type of material of which the conductor is made the thickness of the conductor. The aim of this is to investigate how the length of a wire affects the resistance of it 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.
The purpose of this research is to identify factors commonly responsible for affecting the resistance of current, or flow of electricity, across a wire in an electrical circuit some factors will need to be identified and investigated prior to experimentation. To detect how resistance affects current, i must first discover what factors affect resistance these factors are: length of the wire - if a wire is longer there are more particles for electrons to move through, and therefore more resistance. Below is an essay on resistance of a wire from anti essays, your source for research papers, essays, and term paper examples aim: to investigate how changing the length of the wire affects its resistance. An experiment to investigate the factors which affect the resistance in a wire 1849 words - 8 pages heaters, hair dryers, toasters, oven and electric fires, use a high resistance wire in their elements so that heat is given outthere are four different factors, which affect the resistance in a wire:1.
Electricity, energy and magnetism 9 d factors affecting resistance (1) the nature of the material (2) the thickness of the wire (3) the length of the wire. Like the resistance to water flow, the total amount of resistance to charge flow within a wire of an electric circuit is affected by some clearly identifiable variables first, the total length of the wires will affect the amount of resistance. Investigating factors affecting resistance of a wire essay - investigating factors affecting resistance of a wire aim --- investigate what factors affect the resistance of wire, however in this experiment i am going to monitor how the length of a wire affects the resistance of a wire if the current is kept the same.
