Determine the rms current in an LC circuit powered by an AC power supply. Then find the frequency that will cause a spike in current in the circuit.

What a lovely little applet! You can speed/slow it, change it from AC to DC, plot the voltage as it rotates, change direction, control other information. Real neat.

[Free Registration/Login Required] Learn about how high-voltage alternating current (AC) electricity generated by a power station is converted into low-voltage AC electricity for your home using this interactive simulation. A PDF...

Illustrated explanation of voltage, current, and resistance and the relationship between them.

This site provides a brief explanation of what an AC current is.

This simulation shows a simple circuit consisting of an AC voltage source and, depending on the button selected, a resistor, a capacitor or a coil.

The voltage in AC circuits oscillates at a rate known as the frequency. With an oscilloscope, see and measure the length of time between signals, and calculate the frequency of an AC signal.

A general summary of electrical resistance including a comparison of AC and DC current.

Apart from the piezo generator, all of these generators are based on the same simple design, where magnets are rotated near to coils of wire (Faraday Induction). There is no coil switching so these are AC generators. On magnet movement,...

A short summary of resistance and how it is measured. Including information on AC and DC.

An electrical circuit simulation modeling the behavior of a voltage source attached in a series to a resistor and capacitor.

Circuit analysis is the process of finding all the currents and voltages in a network of connected components. We look at the basic elements used to build circuits, and find out what happens when elements are connected together into a...

AC circuits with capacitors and inductors respond to the frequency, as well as the voltage. Find the frequency value that reduces the circuit power to half the maximum.
