    Factors that Affect the Resistance of Resistance Putty This investigation is designed to look into the resistance of different materials, in this case, resistance putty in the form of wires, and their conducting capability in different shapes. We must bear in mind though that different thickness and length of the putty used to make up the wire itself will affect the electric conduction capability. Therefore, the factors are;  The thickness of the putty e.g. 1mm, 2mm, 3mm in diameter

    Investigate factors that affect resistance Introduction During recent physics lessons, we have been studying resistance and what factors may affect resistance. So far, we have learnt that… à Resistance is the opposition to the flow of electrical current à It is caused by electrons colliding with the atoms in a metal à The more collisions there are, the greater the resistance will be à When electrons collide with atoms, the atoms absorb the kinetic

    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

    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

    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

    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

    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;

    Factors that Affect the Resistance of a Metal Conductor All metals offer some resistance to the flow of an electric current. Several factors affect the resistance: * Temperature * Length * Cross-section area * The metal or alloy the conductor is made of This investigation looks at the effect of length. Background Information ====================== Why does resistance occur? ========================== Resistance occurs because

    Investigating Which Factors Affects the Resistance in a Circuit Aim – To investigate which factors that will affect the resistance in an circuit. Factors – All these things might affect the aim * Material the current passes through * Temperature of wire * Length of wire * Thickness of wire We will change the length and thickness of the wire each time, staring with a set length then changing the thickness, and then starting with a set thickness

    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
