Resistor color code
An animation of current flow through a resistor in which you can change the factors that are denoted by the coloured bands on the resistor and observe the results of your changes.
Resistors
A java applet using several configurations of resistors in parallel, in series or the combination of both and changing the individual resistance.
Ohm's Law
Java Applet simulating a current-voltage experiment for a resistor
Simple AC Circuits
Java Applet simulating the current-voltage relationships for a resistor, capacitor or inductor connected to an AC source.
Impedance
While Ohm's Law applies directly to resistors in DC or in AC circuits, the form of the current-voltage relationship in AC circuits in general is modified where I and V are the rms or "effective" ...
Resistors in series and parallel
A set helpful of simulations and calculations for series and parallel circuits.
Crossover Network
Most loudspeakers use multiple drivers and employ crossover networks to route the appropriate frequency ranges to the different drivers. Combinations of capacitors, inductors, and resistors can ...
Phasor Diagram
It is sometimes helpful to treat the phase as if it defined a vector in a plane. The usual reference for zero phase is taken to be the positive x-axis and is associated with the resistor since ...
Colour Coded Resistance Calculator
A simple program to help students calculate the resistance of a certain resistor. A very easy and simple site that works well and looks good.
OHMZONE
Create a circuit by dragging components (battery, bulbs, wires, resistors, voltmeter, ammeter) on to a circuit board. You can use the ammeter and voltmeter to check the current and voltage at ...
