Ohm's Law
The Basics: Students will gain a better understanding of the relationship between voltage, current, and resistrance as they alter positions of clip leads along a nichrome wire and observe changes in the brightness of the attached bulb. This qualitative approach can be made more quantitative by adding an ammeter and voltmeter to the circuit.

Fuses - Overload Protection
The Basics: There are two types of circuit overload protection: fuses and circuit breakers. Fuses protect circuits by adding a piece of metal conductor (called a “link”) in series with the circuit to be protected. This special metal conducts normal electrical loads well, but in the event of an overload it will heat up and melt, breaking the circuit.

Fuses - Short Circuit Protection
The Basics: A short circuit occurs when an operational circuit is accidentally bypassed (shorted out). The resistance of the circuit is usually reduced to near zero in these very dangerous situations. Fuses are used to prevent damage if a short circuit should occur.
Again connect the Genecon through a steel wool strand to the parallel bulb base. Connect just one bulb and, once again, keep combustible materials away from your link.
Now create a short circuit with a jumper wire as illustrated and start cranking the Genecon.

Capacitance
The Basics: A capacitor is a device which has the ability to store an electrical charge. Traditional capacitors are made of two pieces of metal, called plates, separated by an insulator called the dielectric. The capacitance of a capacitor depends primarily on the size of the plates, the distance between the plates, and the permeability of the dielectric to electric fields. Moving the plates closer together and enlarging the plates are two ways of increasing capacitance.

Connect the Genecon to the capacitor (observe polarity carefully!). Turn the handle while making the following observations:
The handle turns hard at first, then easier as you continue turning.
As the capacitor is charged, the current which the Genecon produces becomes smaller and less energy is required to turn the handle.
This helps demonstrate Len'z Law: because the Genecon uses a magnet to produce a current in a rotating oil of wire, this coil becomes an electromagnet. The magnetic field associated with the rotating coil opposes that of the permanent magnet in the Genecon. Thus, when the capacitor becomes charged, the current through the coil decreases, its subsequent magnetic field decreases, and the Genecon handle becomes easier to turn.]
Discharge the capacitor by shorting out the two leads with a jumper wire for a few seconds.
Connect the Genecon and charge the capacitor again while counting the number of turns. Let go of the handle. What happens?
Remember that the Genecon is also a motor – count the number of times the handle turns by itself. Compare the two turning counts to approximate the efficiency of the Genecon.
