Investigating How Different Lengths of Wire Affect the Resistance in a Circuit Hypothesis: I predict that; the longer the wire, the more resistance there will be. So if the length of the wire were to double, so would the resistance. The reason for my prediction is: The flow of electrons is called a current, the electrons are constantly hitting atoms, which causes resistance. If the same amount of current is passed through a longer piece of wire, there will be more collisions, hence more

The Length of a Wire Affects Its Resistance Scientific Enquiry: I know that metals are good conductors of electricity. Metals are good conductors because their electrons are easily released allowing electricity to flow. The electrons can carry current because they split up from the positive ions, so they are free to move and to carry current. Factors that affect resistance: 1. Length Â– the longer the wire the more atoms there are for the current to push through. 2. Width Â–

Factors Which Affect the Resistance of a Wire To start off this experiment I feel that it is suitable to explain the main facts of this study. Below is a section explaining the resistance in detail. Facts on Resistance: I have shown how resistance occurs. Â· WIRE Â· ATOMS Â· ELECTRONS Resistance occurs when the electrons traveling along the wire collide with the atoms of the wire. These collisions slow down the flow of electrons causing resistance. Resistance is a

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. § I should just leave the batteries connected to the wire only for a short time, as I only need to take a reading and take it off. § I should be careful

Investigating the Factors that Affect the Resistance of a Wire Aim To study the factors which affect the resistance of a wire. Background Information Although current and potential difference measure different things, they are related to each other. In 1826, Georg Ohm discovered that doubling the p.d. doubled the current. (Taken from Ohm's Law: the current flowing through a metal wire is proportional to the potential difference across it (providing the temperature is constant)

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

The Resistance of a Wire How does the length of a wire affect its resistance? Aim: The aim of this investigation is to determine how the length of a wire can affect its resistance. Scientific Knowledge: Resistance means the 'opposition to the flow of current.' Electric current is defined as the movement of free electrons; therefore resistance is the opposition to the motion of free electrons. Ohm's law shows the relationship between the voltage across a given piece of metal

However, the characters of the West weren’t the only things that helped the development of America; many inventions were a part of the development of the West and helped it flourish into a thriving community. Barbed wire, the McCormick reaper and railroads—for example—were a large part of the development in the West—from helping to define claimed land boundaries, agricultural development and competition, and even growth of the West. Claimed land boundaries could only

Investigating What Factors Affect the Resistance of a Wire For this investigation I am going to investigating a factor which effects resistance of a wire. Resistance is measured in ohms (Î©). It is a measure of how hard it is to move current through a component, it occurs when electrons travelling along the wire collides with the atoms of the wire. To choose a factor to measure I will make a list of the factors I could investigate and decide which one is best for me to investigate.

Resistance of a Wire Investigation Aim: The aim of this experiment is to explore the effects of resistance that travels through a constantan wire when induced with an electric current. Introduction Resistance is measured in Ohms (â„¦). The formula for calculating resistance is: V=IR R=I/V I=V/R An electric current is commonly described as the 'flow of a sea of electrons'. Electrons are inside an atom, they are very small in size, and extremely small in weight compared to

Investigating the Relationship Between the Length and Resistance of a Wire I am going to investigate to see if the change in the length of a wire will affect the size of a current My prediction ============= I predict that the longer the wire is the higher the resistance This is because there are free moving electrons being resisted by the atoms in the wire, which is converting electric energy to heat energy. So if the wire is longer there’ll be more electrons to collide with therefor
