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 current is the rate of flow of charge through a conductor, and it is measured in amps using an ammeter. We will write a custom essay sample on the resistance of a wire make sure you measure the nichrome wire with a ruler to exactly 1 metre (100 cm, or 1000 mm) and . Introduction anthony gullan physics coursework an investigation to find the resistivity of wires the experiment the experiment that was used to obtain the results was very simple the voltage and current were measured whilst varying the length of wire. Hows does changing the length of wire affect resistance essay sample measure 100cm of the wire and attach to a metre ruler ÿ check equipment works well.

Free essay: the problem with using resistance as a measurement is that it depends not only on the material out of which the wire is made, but also the. Wire resistance calculator & table expected resistance of: a 2-wire measurement: write an essay response to our question for a chance to receive $1,000 . 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. How does the length of a wire affect its resistance is called the potential difference of the cell and is measured in units called volts essay on resistance .

Resistance of wire essays: over 180,000 resistance of wire essays, resistance of wire term papers, resistance of wire research paper, book reports 184 990 essays, term and research papers available for unlimited access. Resistance of a wire essaysaim: the resistance of a wire depends on certain factors investigate the effect of two of these factors ¡v some variables that will be relevant to this investigation are: of these the variables will be input and output voltages in experiment one, and length and resis. Variables why controlled how controlled length of wire the resistance changes with the length of wire there are different amount of electrons in different length if wires this will affect the accuracy of results if the wires are not measured properly this is an independent variable i will .

The tools you need to write a quality essay or term paper the effect of length on the resistance of the wire 1 r is called the resistance-, measured in . The current through the wire was measured twice and the average taken we will write a custom essay sample on the resistance of a wire specifically for you. How to measure resistance with an digital multimeter, dmm measuring resistance with a digital multimeter is easier and faster than making a resistance measurement with an analogue multimeter as there is no need to zero the meter. Procedure: in order to investigate how the resistance of nichrome wire depends on its length i will firstly have to know the formula for resistance (resistance = voltage ï¿½ current) so, in order to find the resistance of a length of nichrome wire, i need to put the wire in a circuit, and then measure []. A longer wire would have more resistance then that which is shorter thus, the prediction here is that although there will be different resistances between two wires of different dimensions, the overall resistivity calculated for nichrome will be the same, as it is calculated per metre for a uniform cross-sectional area.

Resistance of a wire investigation essays: over 180,000 resistance of a wire investigation essays, resistance of a wire investigation term papers, resistance of a wire investigation research paper, book reports 184 990 essays, term and research papers available for unlimited access. A wire affects the resistance - sample essay to investigate whether or not the length of a piece of a wire affects the resistance background information resistance is a measure of how difficult it is for a current to flow in a circuit. Thickness of the wire: the thicker the wire is the more free electrons in the current can spread out moving over a larger area therefore there is a smaller chance of colliding with the positive ions, thus it decreases the resistance.

Many measurement systems are subject to errors so you should have strong conviction about the expected results if a wire has resistance of 26 ohms, half that length will have a resistance of 13 ohms for sure. The purpose of this experiment was to measure the resistance at room temperature of a lamp we also measured the resistance of a cold lamp compared to the resistance of a hot lamp. Close key k adjust the resistance ##r## from resistance box so that the potential difference across the potentiometer wire is greater than the emf of the cell which is to be measured suppose ##r_p## is the resistance of the potentiometer wire of length ##=l##. Resistance wire coursework as the main topic of universities essay with custom note paper each cost measure is the inverse u shape pattern predicted by theory, the resistance wire coursework course of working.

- I need to measure the resistance of a copper wirei have calculated the resistance value theoreticallyi need to prove it practically is there any.
- The resistance of a wire depends on the number of collisions the electrons have with the atoms of the material, so if there is a larger number of atoms there will be a larger number of collisions, which will increase the resistance of the wire.
- Resistance is a measure of how hard it is to move the electrons through the wire the length of the wire also makes a difference in the resistance because, if the length of the wire is increased then the resistance will also increase as the, electrons will have a longer distance to travel and so more collisions will occur.

Hi cabe, you could measure the resistance, but you would need access to both ends of the wire if you have a good building ground and regulated power supply, you could measure the voltage drop from one end to the other. To measure the resistance of the wire i am going to use the equation resistance=volts current i will obtain the voltage and current readings from the voltmeter and ammeter below is a circuit diagram for my preliminary experiment. To measure the internal resistance of a battery the pd across the terminals needs to be measured as current flows, in this practical the current is varied by changing the length of a piece of nichrome resistance wire connected across the terminals this method assumes you only have one multimeter so .
