First before starting my coursework i have decided to choose a factor that will affect the resistance of a wire i shall do this by going through all of the factors that affect the resistance of a wire and how i would measuring each factor to find out which would be the most effective and easiest factor to measure below is a list of. Introduction to research: in 1911, while investigating the conductivity of various metals at temperatures near the boiling does temperature affect the electrical resistance of a wire, a resistor, and a superconductor” dependence that nearly changed by a factor of three over the temperature range tested (b) the resistance. What is resistance what do we use resistors for does length affect resistance does temperature affect resistance does the type of resistor material affect resistance does the thickness of a we are not going to investigate this factor as it is difficult to control the temperature of a wire in an investigation the last factor. Introduction: resistance is a force, which opposes the flow of an electric current around a circuit resistance is measured in ohms george ohm discovered that a circuit sometimes resists the flow of electricity he called this 'resistance' he even came up with a rule for working out the resistance of a circuit, which was. Background information: all conductors resist the flow of current this is called the resistance of the conductor there are several factors that influence how much resistance is provided by a conductor: atomic/molecular structure of the metal, length and cross-section area part 1: investigating the effect of length on resistance. Resistance all conductors show some opposition to the flow of an electrical current this opposition to current flow is called resistance there are several factors that affect the resistance of a conductor material eg copper has lower resistance than steel length - longer wires have greater resistance thickness - smaller.

The constant is known as resistance r of the conductor t under investigation thus, v/i= r or v= ir hence the slope of a voltage—current graph is equal to the i= v/r i= 12v/8ω =15a factors affecting the resistance of a conductor there are three main factors that affect the resistance of a conductor: temperature. Required practical 3a resistance of a wire for the new gcse in physics this video details the experiment and shows the results to enable you to plot your ow. The overall resistance is the sum of all the resistance values that make up the chain resistance in a conductor is what limits the flow of current through a conductor and is analogous to mechanical friction between objects the variables that affect resistance are the conducting material, the crossection area or thickness of. Class practical a simple investigation of the factors affecting the resistance of a wire.

This video is intended for students to watch and pause as they set up the experiment to find the relationship between resistance and the length of a wire. In other words, the length, cross-sectional area (the area you see looking into the pipe to see what's inside), and stuff inside the pipe all affect its resistance to water electrical resistors are very similar—affected by the same three factors if you make a wire thinner or longer, it's harder for electrons to wiggle.

Soil resistivity is a measure of how much the soil resists the flow of electricity it is a critical factor in design of systems that rely on passing current through the earth's surface an understanding of the soil resistivity and how it varies with depth in the soil is necessary to design the grounding system in an electrical substation,. Factors affecting the resistance of a wireintroduction:resistance is a force, which opposes the flow of an electric current around a circuit 980 words - 4 pages what affects the resistance of a wire planning for the sc1 introduction: in this experiment i will be investigating how length affects the resistance of a wire. It is proposed that there are factors that influence the extent to which metal wires carry electrical current in circuits ie the length of the wire, the cross- sectional area of the wire and the type of material in the wire several expressions link the factors together resistance measured in ohms (ω) is found by ohm's law, r=v/i v. Observe changes to the equation and wire as you play with the resistivity, length, and area sliders.

Investigating the factors that affect the resistance of a wire aim: my aim is to find out how the length affects the resistance of a wire safety: § i should not leave the power coming from the batteries on the wire for too long as this will cause heating and might burn § be careful when touching the wire, as it may be hot. Circuit to collect data on current and voltage, and calculating the resistance of a wire (p4c) affect the gauge of wire needed for good quality sound data to show the relationships between the gauge, diameter and resistance of speaker wires you will the development of the plan and the conduct of the investigation.

- A simple investigation of the factors affecting the resistance of a wire modelling a resistive survey this activity models an archaeological survey (as students in the uk might have seen in tv programmes such as time team) they learn that the resistance between two points depends on the shape and resistivity of the.
- An in investigation into the resistance of a wire aim: to investigate the factors affecting resistance there are four main factors which affects the resistance and they are: the material the cross-sectional area (thickness) the length the temperature but in this investigation i am only going to investigate in the factors length.
- Risk assessment to keep the experiment safe i shall keep electrical conductors away from the plug sockets i will take care not to hurt myself or anybody else with the crocodile clips i will also not turn the power socket on full so as that the wire does not burn or set fire to any surrounding objects or burn anybody preliminary.

Measurement procedure to determine the ac resistance of conductors with large cross sections on production lengths of power cables keywords xlpe cables , ac, alternating current, ac resistance, large conductors, skin effect, eddy current losses, ks factor, milliken, oxidized wires, enamelled wires. Physics investigation: aishwarya moothan (2013) research question what are the factors that affect resistance in conductor would a thick copper wire give less resistance than a thin copper wire background information electrical current is the flow of electrical charge in an electrical conductor current flows. Turns pieces of a clock with electromagnet and coil to make an electromagnet stronger, you can wind a coil with more turns of wire the number of turns multiplied by current in amperes gives ampere-turns, a factor that determines magnet strength. Resistance of the coil it is the purpose of the following theoretical investigation to show how each of these three factors enters and to give an idea of the magnitude of the effects which they produce 1 skin effect the resistance of a conductor for alternating current is greater than for direct current, because in the former.
