SimulationsVisual voltage in a battery -- this simulation is a bit 'corny' with little cartoon people moving electrons, but it gets across the idea that more charge separation is needed for greater electric potential difference (greater voltage). Notice that you can reverse the poles of the battery.
Factors affecting resistance in a wire - this is self-explanatory. Good visual for seeing proportionality. As atoms move quicker, the substance gains heat energy (heating coils in hair dryer) or even give off light (tungsten filament in light bulb). Battery-Resistor Circuit -- looks at relationship between volts, amps and resistance. Visually shows why resistors/loads can heat up. Magnetic induction - Check our 'magnetic induction' on the Gizmo page for good visualization of RHR #1 Phet Visual Electromagnetism - This is a phet simulation that shows a) magnetic field map around bar magnet, b) induced magnetic field (RHR#2) and the field map and c) generator like Niagara Falls among other things. How a TV screen works - How Stuff Works is a great site. Click so see how a CRT TV/monitor works. Click here for a simulation of 'repainting the screen'.
