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.
