  • Circuit With Resistors In Series
    786 words
    Investigation of four resistors connected in series and in parallel. Background: Resistance is what opposes the flow of electrons in an electric current through a conductor. Resistors are conductors that have a high resistance. A conductor is the material through which an electrical current flows. The Resistance, (R) of any conductor is given by the equation = V / I where V = p. d. across the conductor I = current according to Ohms Law V = I / Rain: The aim of this experiment is to investigate h...
  • Plot Resistance Versus Cross Section
    1,846 words
    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 because as the electrons move through the material (onc...
  • Resistance In The Ghettos
    1,529 words
    Question of Survival Jewish Resistance We must first realize that resistance was in no way a survival strategy. Yet, even when it seemed obvious that death was near inevitable, why did they not put up a fight? This argument is still puzzling to many holocaust historians, yet the arguments of Raul Hilberg and Yehuda Bauer offer insight to possible reasons why they did not fight and that resistance was more widespread than most people think. First of all we will look at Raul Hilberg's "Two Thousan...
  • Resistance Of A Wire
    735 words
    Physics Plan - Resistance of a Wire Aim The aim of my investigation is to investigate how length affects the resistance of a wire. Theory The four factors that affect the resistance of a wire are: o Length o Material o Temperature o Cross section Resistance is the force, which opposes the flow of an electric current around a circuit so that energy is required to push the charged particles around the circuit. Resistance is measured in ohms. Resistance occurs when the electrons travelling along th...
  • Resistance Of A Wire
    2,359 words
    What is Resistance? Resistance is caused by collisions between the atoms in the object and the electrons (carrying electricity), which are trying to move through the object. (R = resistance measured in ohms (W) ). Basically resistance is the term used to describe an objects resistance to the flow of electricity Electrons lose their drift velocity only when they collide. The electrical resistance of a conductor is simply a measure of the potential difference required to maintain a current. Basica...
