    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 – the longer the wire the more atoms there are for the current to push through. 2. Width –

    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. · WIRE · ATOMS · 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

    How Thickness and Length Affect the Resistance of a Wire I plan to investigate how the length and thickness of a wire affects the resistance. I plan to do this by keeping the voltage the same by using a variable resistor and measure the current when varied lengths and thicknesses of wire is in a circuit ===================================================================== Variables ========= There are a few factors that can affect the resistance. These are; * Temperature

    Width of Copper Wire Affect the Current of a Circuit Task: To investigate how length and width of copper wire affect on the current of a circuit. Prediction: In this experiment, the input variable will be changing the length of the copper wire used in the experiment, and also the SWG of the wire, which means the width of the wire. By changing this variable, the current the circuit will vary. With my knowledge in science and some research on the factors that affect a circuit's resistance

    Factors that Affect the Current Needed to Melt a Wire Aim: Investigate one factor that affects the current needed to melt a wire. Plan: I am going to investigate what factors affect the current needed to melt a wire. In this investigation, I have decided to change the thickness of the wires that I use, and then while increasing the resistance, I will measure the current needed to melt the different wires. I will start with the variable resistor set to the maximum. I will slowly decrease

    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
