Hi Hector,

"Coils do dissipate energy, charged capacitors dont !"
Agree when using practical coils. Ideal coils don't dissipate energy. This is actually used for testing for superconductivity. Inducing a current in a superconductor makes the current continue and thus makes the superconductor perform like a permanent magnet. If there is the least resistance the energy will be transformed into heat and thus dissipated. This makes a voltage gradient along the resistance and then disproves the sample as being superconductive.

"that is true as I have stated standard tolerance values escape ZPE design character needs in terms of accuracy and % of tolerances required for ZPE device replication..

even physical  location of device may make & makes tuning  the non operating machine back to standard a nightmare ...

Apropos when trimming tolerances. Here is an article about the art of soldering micro electronics where the author mentions that trimming can be performed by adding or removing a bit of solder: 'Fortunately, in soldering (as in RF layout and pretty much every practice dealing with electromagnetic signal flow), beautiful work always wins. Symmetry and neatness can be easily backed by theoretical and experimental evidence that proves their necessity. For example, an asymmetric solder means that the PCB side with excessive soldering will modify the electrical properties of the part.'

And:
'On a more complicated level, there is the soldering of an IC package. For example, my soldering mentor told me how an R&D project used the excess soldering to improve matching network characteristics.'

 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 do dissipate energy, charged capacitors dont !

Coils and capacitors are diametrically opposites of each other. What current is for a coil voltage is for a capacitor and vice versa.

OK ! 

 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.

Refer to rotary power systems as this does not quite make it 

Real coils and capacitors have resistance because they are made of metals having resistance (usually copper and aluminum or tantalum).

Coils do have permanent resistance  , capacitors don't only temporary as they charge up and its Z  (impedance ) 



 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. 

partially true .. 

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.

 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 ?
