Electrostatics -
Electric Fields -
Electric
Fields 1- Shows the field lines, and the field direction at any
one point (the resultant). Be sure to drag the charge around. Obviously,
for maximum learning: read the instructions.
Electric Field Game - This is AWESOME!!!! Move your mouse across the blank page and it will show you the direction of the electric field at that point. Try to figure out which type of charge or charges are making this field. HINT: the choices show only the number of charges. If there are two positive charges, for example, they could be anywhere.
Electric
Fields 2 - Will show you the direction and strength of the field.
Capacitors -
Very thorough capacitor overview
Capacitor 1 - (included in the above overview) Instructions: there is a control slider just below the left corner of the picture. 1. Move the slider to the right and the battery pushes electrons to the negative side of the capacitor. 2. Move the slider back to the middle and the battery is disconnected, while the capacitor remains charged. 3. Move the slider to the left and the capacitor discharges back.
Capacitor 2 - Great Applet!!! When you click the red switch the battery starts charging the capacitor. You will see the electrons flowing. IMPORTANT: notice two things: 1. over time the number of electrons flowing decreases as the capacitor charge increases; 2. the voltage of the capacitor keeps increasing until it equals that of the battery. Click the red switch again and the capacitor discharges (loses its charge). Study this one!!!
Capacitors applets and explanations .
Variable Capacitor - Only shows that more area produces more capacitance.
