    Voltage: Ohm's Law and Kirchhoff's Rules ABSTRACT Ohm's Law and Kirchhoff's rules is fundamental for the understanding of dc circuit. This experiment proves and show how these rules can be applied to so simple dc circuits. INTRODUCTION In the theory of Ohm's Law, voltage is simply proportional to current as illustrated in the proportionality, V = RI. As shown in this relation, V represent voltage which is the potential difference across the two ends of a electrical conductor and between which an...
  • Electrical Properties Of Semiconductor Material
    1,846 words
    Semiconductors are either solid or liquid material, able to conduct electricity at room temperature more readily than an insulator, but less easily than a metal. Electrical conductivity, which is the ability to conduct electrical current under the application of a voltage, has one of the widest ranges of values of any physical property of matter. Such metals as copper, silver, and aluminum are excellent conductors, but such insulators as diamond and glass are very poor conductors. At low tempera...
  • 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...
  • Light Bulb At Different Temperatures And Currents
    1,468 words
    Physics Project The Planning Key V A Variable resistor Ammeter Light bulb Voltmeter I am carrying out an experiment to find the different resistances created by a light bulb at different temperatures and currents. Because of the nature of a light bulb, it glows white-hot when fully on, the resistance will change at different currents. When the current is low and the bulb is not very bright, it wont be as hot and therefore it will have less resistance. But when the current is high and the bulb is...
  • Current In The Parallel Circuit
    803 words
    Ohm's law states that current in a resistance varies in direct proportion to voltage applied and inversely proportional to resistance. It is the relationship between voltage, current, and resistance. (V = IR) When more then one resistor is connected to a circuit they can be in either series or parallel patterns. A series circuit is one that the components are connected end to end so that current has only one path to follow through the circuit. In a series the current entering each resistor is th...
  • Result For The 1 Ohm Resistor
    3,122 words
    Aim: To investigate the relationship between Current and Voltage Scientific Knowledge The current and voltage of an electric circuit, is given by the formula V = IR. This is known as Ohms. Ohms Law is only applicable, when the temperature of the resistor is kept constant. Therefore Ohms law is only applicable to Ohmic conductors. An example of Ohmic conductors are metals and alloys at constant temperatures. Anything that doesnt obey Ohms law, are know as non-Ohmic Conductors. An example of these...
