L3 Electromagnetism
Electromagnetism Unit:
Internal resistance & Kirchoff:
DC circuit builder (Phet): use "lab" with ammeter & voltmeter and turn on "battery resistance"
Capacitors (DC):
Capacitor Lab (PHET) changeable voltage, area, distance AND discharge through bulb
Capacitor Lab with dielectric effect (PHET) - uses java
Dielectric and Series vs Parallel Capacitor Lab (PHET): with V, Q and E stored as you slide dielectric into capacitor as well as series vs parallel capacitors
Charge/Discharge graphs: Falstad's circuit simulator: drop-down menu: Circuits: Basics: Capacitor
Charge & discharge capacitor (HKNG): download & run java file: 3 graphs at the same time!
Factors that affect capacitance (Florida State Uni)
Charge & discharge capacitor (Florida State Uni)
time constant graph of charging capacitor (Florida State Uni)
Inductors (DC):
Induced voltage from L2phy that can be explained by change in flux! (HKNG)
Faraday's Law (HTML5 PHET) bar-magnet & inductor
Induction (Geogebra) bar-magnet & inductor
Lens' Law (FSU) showing direction of induced current
DC incuctor current-time graphs: Falstad's circuit simulator: drop-down menu: Circuits: Basics: Inductor
Faraday's Law (java PHET): better but need to download and run java
AC Generator (Fendt): for change in flux creating back EMF
Another generator (Duffy): graph of flux vs time and current vs time

AC circuit with either R, C or L with phasors! (Mag Lab) warning: current is ALWAYS a sine wave in NZ...
AC circuit simulator (Phet) java download & run
Circuit simulator (Falstad) select "circuit" dropdown menu, then "A/C circuits"...
