Investigating length wire affects resistance

investigating length wire affects resistance A piece of thin wire has higher resistance than a thicker with the same length, which means that it's length increases the thickness decreases is greater thick because apparatus wires varying.

Thanks a2a suppose you have a wire of 10 gm weight and its length is 10 cm now if you increase the length of this wire to 20 cm its resistance r will be twice than it was at 10 cm. How the length of a wire affects its resistance in my physics coursework i am going to investigate the effect of the length of a wire on its resistanceresistance is the measure of how easy it is for current to flow through a wirecurrent is the rate of flow of charge through a conductor, and it is measured in amps using an ammeter to help me plan my investigation i have completed a. The connection between current, voltage and resistance was discovered in 1827 by georg ohm, a german physics and how does length affect resistance when the length of the wire increases, resistance increases. Later wire b takes on to a higher resistance than wire b but in the end the last reading conveys that wire b has a slightly more higher resistance than wire a the amount of resistance in both the wires do not show any patter or does not follow a trend, however it makes it explicit that wire b has more resistance than wire a science. There are a few factors that affect how much resistance electricity encounters, including the width of the wire, the wire material and the length of the wire a longer wire requires more width and should be made of a material that is highly conductive to cut down on resistance.

Resistance vs length obtain various lengths of the same gauge copper wire (we used 02, 04, 06, 08 and 10 meter lengths of 22-gauge wire) set up a series circuit using a 3-v dc power supply, a current probe (ammeter), a 10 ω resistor, and one length of the copper wire. Gcse physics coursework - resistance of a wire coursework resistance of a wire task to investigate how the resistance of a wire is affected by the length of the wire. Therefore i predict that the resistance of the wire will increase as the length increases because each electron must travel further throughout the wire and are therefore exposed to more ions and electrons which is equivalent to more resistance.

In my physics coursework i am going to investigate the effect of the length of a wire on its resistance 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. To investigate the factors of affecting the resistance of a wire essay sample aim: to investigate the factors of affecting the resistance of a wire in this experiment i will be using a metal nichrome wire to show the resistance when the length and width is changed. Extended experimental investigation: wires carry electrical current in circuits ie the length of the wire, the cross- the influential effect it has on resistance (virtual institute of applied science) the relationship between length (l) and resistance (r) is shown in figure 2.

For example, when the length of the wire is 20cm the resistance is 314 ohms when the length of the wire is 40cm the resistance is 618 ohms, which is roughly double in my main investigation i will see if this observation applies to my results. For each wire plot a graph of resistance (y-axis) against length the resistance of a wire is given by the equation: r = ρ x l/a where r is resistance, ρ (pronounced 'rho') is the resistivity of the wire, l is length and a is its cross-sectional area. First, the total length of the wires will affect the amount of resistance the longer the wire, the more resistance that there will be there is a direct relationship between the amount of resistance encountered by charge and the length of wire it must traverse. The maximum and minimum values for resistance (maximum resistance at maximum length and vice-versa) were as follows: constantan (0 and the maximum and minimum resistance values indicated that changing the distance does have the same effect as changing the length of the wire may affect the resistance and current readings0 the multimeters.

Does the length of a wire affect its resistance like the resistance to water flow, total amount of charge flow within a wire an electric circuit is affected by some clearly identifiable variables. I am going to investigate what factors affect the resistance of a wire there are three main factors which affect the resistance of a wire: (the more the electrons bump together, the higher the resistance) the length of the wire will make a difference this is because when you have a long wire, the electrons have to squeeze. Some of the concepts which might be introduced for the first time in natural sciences, have already been covered in the technology curriculum how does the diameter or cross-sectional area of the wire affect the resistance of the wire investigation: how does the length of the wire affect the resistance of the wire. I predict that the longer the length of wire, the higher the resistance is i think this because there are more metallic atoms in the wire, these will obstruct he electrons trying to get through more.

Investigate how length affects the resistance of a length of wire had to be placed in parallel and the ammeter, which had to be placed in series draw up a rough table onto a piece of paper with the appropriate headings. I am aiming to investigate the factors that effect the resistance of a piece of wire i will be focusing on the thickness of the wire but will also take the length of the wire into account. The experiments will be investigating the relationship between the thickness of the wire and the length of the wire i will connect up a circuit like shown above, the power supply coming from a power pack.

Investigating how the length of a wire affects its resistance a constant should be able to be calculated from the results firstly, we need to define the variables which will be kept the same or varied in order to correctly write the method. Resistance lab report factors affecting the flow of electron affect resistance experiment 1 design aim to investigate the relationship between resistance and the length of the wire hypothesis the longer the length of the wire, the higher the resistance variables ways. To investigate how the length of a nichrome wire can affect the resistance of a wire i will also observe the thickness has any effect on resistance and length we will write a custom essay sample on factors affecting the resistance of a wire specifically for you for only $1638 $139/page order now search.
