According to the patent office, "laws of nature, physical phenomena, and abstract ideas are not patentable subject matter." If the theorem is embodied in a new useful process or device, that process or device could be patentable, provided the application meets all the other legal requirements.

What is Foster's reactance theorem?
Foster's reactance theorem states that the reactance of a passive, lossless two terminal network always strictly monotonically increases with frequency. This is a very important theorem in the fields of electrical network analysis and synthesis.Ê
What has the author P Penfield written?
P. Penfield has written: 'Tellegen's theorem and electrical networks'
In 1917 what company introduced the portable electrical drill complete with a patented pistol grip and trigger?
Black and Decker
Is the efficiency with which a generator in the hub of a wind turbine converts shaft power to electrical power subject to Carnot's theorem?
No. Carnot's theorem applies to heat engines - machines that convert heat to other types of energy.
Why is Nicola Tesla important to electricians today?
He was that patented the electrical system used to light up houses and buildings around the world.
Is the Maximum Power Theorem verified experimentally?
Yes, the Maximum Power Theorem has been verified experimentally in electrical circuits. By adjusting the load resistance in a circuit, the theorem predicts the maximum power transfer to the load when the load resistance matches the source resistance. This has been demonstrated in practical experiments.
Who invented resisters?
Otis F. Boykin invented the electrical resistorand patented it on Feb. 21, 1961. He invented a total of 28 electronic devices
In May 1896 what patent did Edison apply for regarding the electrical lamp?
In May 1896, Edison patented a fluorescent lamp that used X-rays.
What is the difference between the thevenin's theorem and norton's theorem?
Thevenin's theorem and Norton's theorem are both techniques used to simplify complex electrical circuits. Thevenin's theorem states that any linear circuit can be replaced by a single voltage source (Thevenin voltage) in series with a resistance (Thevenin resistance). In contrast, Norton's theorem states that the same circuit can be simplified to a single current source (Norton current) in parallel with a resistance (Norton resistance). While they are mathematically interchangeable, Thevenin's focuses on voltage sources, while Norton's emphasizes current sources.
Who patented the Saxophone and in what year was it patented?
The saxophone was invented by Adolphe Sax and he patented it in 1846.
Was cheerleading patented?
No cheerleading is not patented, it is not able to be patented as it is not an object or product. However cheerleading related clothing items, designs, and toys can be patented
What Austrian born electrical engineer who patented a form of spread spectrum still used in wireless communications has a star on the Hollywood Walk of Fame?
