The Relationship Between the Length of Constantan Wires in a Circuit and the Current Aim To investigate the relationship between the length of constantan wires in a circuit and the current flowing through. Introduction ============ In a conductor electrons are able to jump between atoms. However in insulators they remain around a single atom unable to move. Constantan, a metal, unlike most other metals is a poor conductor although it is also a poor insulator. Being a metal it

Investigating how the Resistance of a Constantan Wire is Affected by Its Length Introduction: In this experiment we will be investigating how changing the length of a piece of Constantan wire will affect the resistance. Therefore the length will be an independent variable and all of the other variables we will try to keep the same. The other variables included in this experiment are temperature, thickness of wire and density of wire. Resistance is a force, which opposes the

Resistance of a Wire Aim Which factors affect the resistance of a wire? Prediction I believe the factors which affect the resistance of a wire are: 1. The length- the increase in length could increase the resistance. 2. The thickness of the core. 3. The material of which the wire is made up of- e.g. Copper, constantan and nichrone. 4. The number of strands within a wire: 5. The amount of current flowing through the wire. For this experiment, the factors which will be

• ## The Resistance of a Wire

The Resistance of a Wire Planning These are the four factors that can affect the resistance of a wire. How thick the wire is How long the wire is Factors that can affect resistance The heat of the wire What the wire is made of Background theory In metals the molecules are usually single atoms and electrical forces hold these together. The atoms are packed tightly together in a regular pattern and electrical forces hold these together. The tight packing causes outer electrons

• ## Checking the Resistance through Wire

810 Words  | 4 Pages

the Resistance through Wire We are using constantan wire to check the resistance thought wire; our variant is going to be the different length of wire. We choose this because it seemed like an interesting variant and it might proof to me that in certain cases it would be more acceptable and also safer to use for example a longer piece of wire rather then a smaller one. To do our experiment we will use the following apparatus Â· Power pack Â· Constantan wire Â· Amp meter We as

• ## Resistance of a Wire

Resistance of a Wire Plan In this investigation, we will be studying the resistance of a wire. The resistance of a wire depends on many factors, some of these include; * Length of the wire * Thickness (diameter) of the wire * The material of the wire * The temperature at which the wire is kept Resistance can be explained as opposing the flow of electric current around the circuit so energy is required to push the charged particles around the circuits. This will then cause

Investigating How the Length of a Wire Affects Its Resistance Planning: Risk Assessment: * I will handle the power supply carefully. * I am going to only use a maximum voltage of 2 volts. * I will be careful when handling the mains equipment. * I will make sure I have a clear space to work in and nothing on the floor around me. In this investigation, I will set up a simple circuit to be able to read the voltage and current when the length of wire changes, so I then can work out

Resistance of a Wire Aim The aim of this investigation is to find out the cross-sectional area of a wire affects its resistance. Diagram Equipment Â· Voltmeter Â· Ammeter Â· 100 cm resistance wire (variable thickness) Â· Power pack Â· Micrometer Â· Crocodile clips Â· Meter ruler Method Â· Set up the circuit as the diagram above shows with the smallest thickness of wire first. Â· Set the voltage on the power pack to 6V. Â· Record the actual voltage supplied

Wire Resistance Investigation I am going to investigate the factors that affect the resistance of a conducting wire. Wire Conclusion From the graph, you can see that as the length of the wire increases, the resistance increases. Due to some results which didnÂ’t fit in, I had to draw a line of best fit. In my hypothesis, I predicted that the effect of changing the wire length will be that as the length increases, the resistance on the wire will increase. This, following my results

• ## Investigating The Resistance of Nichrome

409 Words  | 2 Pages

Investigating The Resistance of Nichrome We used different pieces of wire that were also of different material that were roughly the same length and we tested the resistance of the different material wires. We recorded results of resistance for 2 different lengths which were 10cm and 20cm we did the experiment twice for each piece of wire. Preliminary Results: Length Copper Iron Constantan Nichrome 10cm (1) 0.3 0.5 1.1 2.3 10cm (2) 0.4 0.4 1
