    The objective: Through a scientific invention the student will create a model that transmits electrical current and demonstrate that electricity travels in a closed path. Materials: (6) light bulb, (6) battery, (6) 6 in. insolated copper wires, (6) wire stripper, (6) switches, (21) safety goggles, (21) aprons, and boxes of gloves. Vocabulary: Circuit, closed circuit, open circuit, electrical circuit, electromagnetic, and parallel circuit Engaged: We are going to do a KWL chart to find out, what you know about electrical current, what you want to know, and what you have learned. What do you know about electrical current? Is electricity something that can be seen? Can someone tell me what is electricity? Can you give me examples of electric current? Students I have a discrepancy event that I want you all to see. The materials that we need for this event is a battery, copper wire, and magnets. Can you think of a way that we can make…

  • Ohm's Law: Explain The Relationship Between Electric Current, Voltage, And Resistance

    Ohm’s law is the basic rule of the electricity that explains the relationship between electric current, voltage, and resistance. The ohm’s law was named after the German physicist Georg Ohm who discovered this rule or law. Ohm’s law statement Ohm’s law states that the electric current flowing through a conductor is directly proportional to the voltage and inversely proportional to the resistance. In other words, the electric current flowing through the conductor increases with increase in…

  • Michael Faraday And Oersted Compare And Contrast

    born in London on September 22, 1791. He was the first person to produce an electric current from a magnetic field, He discovered diamagnetism and explained why some substances react opposite to a magnetic force when they encounter a magnetic field. He also discovered the effect of magnetism on light and he invented the electric generator and the electric motor.…

  • Permanent Magnet Research Paper

    They produce magnetic fields by their electrons spin in the same direction as their nucleus and create small magnetic fields. When they truly arrange themselves, they can produce a single magnetic field over all. Some permanent magnets are used in the basis of electromechanical device. The electromagnets are magnets controlled by electricity and the electrical current makes a magnetic field. They use negative and positive poles to make the magnetic fields. Some soft magnetic metals can be…

  • Oersted's Theory Of Magnetism Essay

    Davy ran into another problem that needed to be answered. Why was the needle attracted to the wire? It was not enough to just say that the electricity and magnetism affected each other. He needed evidence that supported his claims. Davy proceeded to throw “some iron filing on a paper, and brought them near the communicating wire, when immediately they were attracted by the wire, and adhered to it in considerable quantities… depended entirely on the passage of the electricity through the…

  • Lab Analysis Of A Circuit Lab

    For the circuits, I noticed the resistors demonstrate Ohm’s Law and the currents/voltages demonstrate Kirchhoff’s law. I also found that the LED’s brightness changes with the amount of current that flows through it. The more current that flows through, the brighter the LED becomes. I also noticed that in most of the circuits, the measured values were different than the nominal values because there was resistance found in the wires. This results a loss of energy from the…

  • Difference Between Parallel And Dc Circuit

    circuit is a circuit in which current can only flow in one direction, constantly and with constant polarity. As opposed to alternating current, which changes its flow direction at regular intervals and can also increase or decrease in value. In this essay I will be mainly describing DC circuits wired in series, parallel, and series-parallel. In a DC series circuit the components are all wired together from end to end with the same amount of current flowing through each component. In a simple…

  • Magnetic Propulsion Essay

    Magnetic propulsion Magnetic propulsion refers the use magnetic energy to move objects from one point to another. Due to increased demand for clean energy, the use of electromagnetic propulsion will also be a new way of powering the future vehicles. This method employs the use of electrical current to create an opposing magnetic field that results in repulsion. The electromagnetic propulsion has been in use in motors to create a rotational force which drives the vehicles wheel forward.…

  • Maxwell And Faraday Research Paper

    possibility because of the observations he made during an experiment. He Placed a wire above a compass and passed a current through the wire. He noticed that the needle of compass moved when current was passing through the wire. André Ampère was greatly inspired by Oersted’s findings and worked on it to create a mathematical formula that later became Maxwell’s fourth equation of electromagnetism in the year 1821. (Peters, 2000) Around the…

  • Difference Between Terminology And Unit

    Terminology and units Current Current is a flow of electrical charge carriers, usually electrons or electron-deficient atoms. The common symbol for current is the uppercase letter I. Potential difference The potential difference between two points.The units for potential difference are Joules per coulomb, or volts. (1 volt = 1 Joule/coulomb). Electrical charge Electric charge is carried by the electrons ( negative charge) and protons (positive charge) within an atom. The…
