Displaying results which match all of the below:
  • Capacitor charge discharge

    Charging and dischasrging graphs for a capacitor circuit.

  • Capacitor charging

    Switch on the circuit and watch the potential across the capacitor and resistor change with time. The resultant graph can be used for further calculations.

  • Charge and field plotter

    A great little animation. Place charges on the page and use sensors to show the direction of the E field or the plotter to plot field lines.

  • Current / water analogy

    An analogy using water flow to represent the current flowing in a D.C. circuit. (Current is the rate of flow of charge). Another flash from David Harrison.

  • Dees cyclotron

    A simple flash movie of a cyclotron. A charged particle is accelerated by an alternating field (square wave) between the two dees and then bent by a magnetic field in the D. The3 radius increases as the particle energy increases.

  • E field - oscillating charge

    A simple animation to show how an electric field is influenced by a charge oscillating in one plane.

  • Induced current

    A simple animation showing that a current is created when a magnetic field is moved through a coil of wire.

  • Oscilloscope - fast, a.c.

    Oscilloscope with a.c. input and faster timebase. Try checking the setting with a stopwatch.

  • Oscilloscope - no input

    Adjusting the timebase for an oscilloscope. Try checking the settings with a stopwatch. Note the scale changes automatically (eventually)

  • Oscilloscope - slow, a.c.

    Oscilloscope slow timebase with a.c. input.

  • Point Charge Electric Field

    Different representations of the electric field due to a point charge - another excellent flash file from David Harrison.

  • Resistance

    Another animation showing the relationship between Potential, current and resistance. Try adjusting each and see what happens.

  • Resistivity

    An animation to show the relationship between resistance, resistivity, length and area. Try adjusting each in turn and see what happens.

  • Simple Buzzer

    An example of the circuit for a simple buzzer. Making the circuit causes a field in the coil which attracts the clapper and hence breaks the circuit restarting the entire process.
