OleNow for the big question.Using the rules, why does Hector's RV work? It most certainly does, as I have tested it myself, quite carefully. I achieved 1.614 times more than was feeding it, a little less than others, who got 1.618, but that is close enough for validation.Why does it work?By understanding, perhaps we can use it better?Cheers Warren

Hi James,

Ideal coils as well as ideal capacitors are pure reactive components meaning they don't dissipate energy. They just store the energy. Coils and capacitors are diametrically opposites of each other. What current is for a coil voltage is for a capacitor and vice versa. This can be shown when making a circuit of just one capacitor and one coil (inductor). Applying energy to such a circuit (LC-tank) will make it oscillate continually if the energy isn't dissipated which requires some resistance. The energy is oscillating between fully magnetic (current or amps) and fully electric (tension or voltage). Thus for a coil the tension doesn't represent energy stored but only how fast the energy is moved which is the power. For a capacitor the current doesn't represent energy stored but only how fast the energy is transferred which is the power.

Real coils and capacitors have resistance because they are made of metals having resistance (usually copper and aluminum or tantalum). The resistive part is called the parasitic part when dealing with both capacitors and inductors. Inductors also have a capacitive part (between the turns as well as to the ambient) which is also a parasitic part when dealing with inductors. Capacitors also have an inductive parasitic part because when current enters them a magnetic field is created around the current path which is inductive. Even resistors have parasitic parts of inductance and capacitance because of the same reasons. Thus all the three fundamental components of electronics (i.e. the resistor, capacitor and inductor) have parts of each other intrinsic to them.

Calculating a circuit is way easier when dealing with only the ideal parts of the components. When building the calculated circuit some surprises may arise because of omitting the parasitic values in the calculations. This becomes more distinctly the higher the working frequency or the faster the switching transitions of the circuit. Even the wires or leads connecting the components have resistance capacitance and inductance. For the theory behind it for example read Ivor Catt about electromagnetism.

Regards
Ole

Norm read Thu it and nothing about voltage .as far as there concerned voltage doesn't exist ? With I think is bs .with out it there's no Watts all current and no volts ?? Well I kept looking and ..

By using a battery with a greater voltage the strength is increased. You can also add more batteries to a series circuit to increase the strength. What factors affect the strength of an electromagnet? By increasing the number of coils of wire around an object can increase the strength of the electromagnet. How would they Dodge this ?
