Current and voltage also with the length of wirefrom which we Investigating resistance essay work out resistance of the wire. The theory behind electricity and conduction supports this too: Overall it was a good and accurate experiment.

On the other hand, more repeats could have made the Investigating resistance essay less accurate due to almost all the results being slightly inaccurate. How to cite this page Choose cite format: Hire Writer I will connect this into the circuit using crocodile clips, I will stretch the wire across a meter stick and connect one crocodile clip at 0cm and one at 10 cm, I will record a reading from both the ammeter and the voltmeter, I will then move the crocodile clip which is on 10cm to 20 cm and again take a reading from both the ammeter and the voltmeter before recording the results into a table.

We had preliminary work to back up our data, conducted repeats and made sure it was a fair test. From these tables and charts we can see a correlation. We collected reliable data easily and quickly, without any problems. I predict this will happen because Resistance is due to the atoms in the wire.

Using our procedure of connecting the circuit, collecting relevant data and then repeating the process, we collected the relevant evidence: To provide extra evidence, more repeats could have been done, and an extra experiment on different types of wires, seeing how the material affects resistance.

I will now go on to plot the graph before recording my conclusion. A cell connected to an ammeter and a piece of wire in series, and a voltmeter connected outside the circuit so that the voltage and current will not change due to their presence. The evidence we have collected is sufficient to support our theory, and although we do have one large anomaly and a few small ones, we also have a few perfect examples of direct proportion.

Conclusion After recording my results and plotting the graph I can say that my prediction was correct.

We also conducted preliminary work on this investigation about thickness of wire. Our procedure was good too, but more repeats could have been done to make sure it was a fair test. If the wire is longer, then there are more atoms in the way of the charges so the resistance will increase.

The resistance will depend directly on the number of atoms in the wire.

An example of this would 30 and 60 cm: This is directly proportional, since when the wire is doubled the resistance is too. The variable for my experiment will be the length so to keep it a fair test I must use 10 cm jumps each time, use the same metal each time meaning it Investigating resistance essay be Nichrome of 0.

Mostly the experiment was a success. This shows that resistance is greater the longer the wire is because there will be more atoms for the electrical charges to hit the atoms and get slowed down. To do this, we will set up a circuit: I have indicated in the rough graph below on what I think will happen and what it will then look like on the graph.

From what my results say I am willing to predict that if I had a thicker piece of Nichrome say 0. These results can now be plotted on a graph: This conclusion supports and proves my prediction fully, as we can see from the graphs and results.

The main anomaly appears to be the metre value, since the resistance is quite far under direct proportion. I predict that the longer the wire, the higher resistance will be. The correlation also appears to be directly proportional from X to Y, which means that there is an equal rate of increase in resistance.

This is based on our preliminary work on how the thickness of wire affects resistance. An example of this would be if a 10cm wire had atoms, a 20cm length of that wire would have 16, The range of results we will be collecting will be from 1m to 10cm of wire, measuring every 10cm.Resistance is a property of a substance that conducts electricity.

Resistance opposes the flow of electricity through conductors and it depends on the PHYSICAL NATURE of the particular conductor. Investigating Resistance of a Wire Essay examples - Investigating Resistance of a Wire INTRODUCTION This investigation is about find the resistance of a wire.

Resistance is the slow-down of the flow of an electric current around a circuit so that energy is required to push the charged particles around the circuit. 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. Free College Essay Investigating the Resistance of Wire.

Investigating the resistance of a wire. Planning For this investigation there are a number of variables that can be chosen /5(1). Investigating the Factors Affecting the Time Peiod of a Pendulum Essay - Investigating the Factors Affecting the Time Peiod of a Pendulum Aim: To investigate the factors affecting the time period of a pendulum Introduction: [IMAGE]The time period of a pendulum is the amount of time that a pendulum takes to swing from position A, through.

In this investigation, we are investigating how the length of wire affects resistance current and voltage. We can change the size or number of cell(s), the length or thickness of the wire, and the length of the circuit.

To do this, we will set up a circuit: A cell connected to an ammeter and a piece of wire in.
