factors that affect the resistance of a piece of wire; the one I am investing is the length at constant temperature. My objective in this experiment is to investigate one of the factors that affect the resistance of a piece of wire. The factor I chose was length. Factors: There our four different things that affect the resistance of a wire: 1. The Length because the wire is thinner than the rest of the wires the electrons wood have more trouble going through for if the wire had the same

Factors Affecting The Resistance Of Wire Aim: To investigate the factors that affect the resistance in a conductor. The main factors that affect the resistance in a conductor are: · Length · Temperature · Cross sectional area · Material · Magnetism The factor that we are going to change is the cross sectional area. Hypothesis: I think that the higher the cross sectional area‚ the lower the resistance in the conductor will be. This is because the Resistance in a metal conductor happens

factor that affects the resistance of a wire. Reworded: I am going to investigate if changing the length of a wire changes its resistance. I predict that the longer the wire‚ the more resistance it has. Planning and Preparation Independent Variable: The variable I changed was length (cm). Dependent Variable: The variable I measured was resistance (Ω). Fixed Variables: The variables I kept constant to make it a fair test; were‚ the type of wire (nichrome)‚ the thickness of the wire‚ and the temperature

Investigation: how the resistance in a circuit varies with the length‚ thickness and type of wire Introduction A current is a flow of negative electrons around a circuit or electrical pathway. This is measured in how many electrons per second or the charge they are carrying go round the circuit (amps or amperes) Voltage or Potential Difference measures how much energy individual electrons have to use up as they go around a circuit. (Volts) Components in a circuit have a Resistance value which

An experiment to investigate the factors which affect Resistance in a wire What is resistance? A potential difference (V) applied across a wire of length (l)‚ there is in the conductor‚ an electric field (E). In this electric field the free electrons are not however under continuous acceleration (Ee/m). This is because they repeatedly collide with the moderately massive vibrating atoms losing their kinetic energy. The vibrating atoms having gained this kinetic energy now vibrate more. The resulting

How Does The Diameter Of Wire Affect The Resistance In A Circuit? Introduction: Some metals such as copper‚ silver and gold are very good conductors of electricity. This is because they all have only one electron on the outer shell. This means that they need only a tiny amount of energy in order to allow the electron to move. Non-metals‚ however‚ do not have free electrons‚ so even non-metals that only have one electron on their outer shell can still hold onto them tightly. Aim Of The Investigation:
