Capacitors have two types of connection: series and parallel.
Serial connection. In this case, the negatively charged plate of one capacitor is connected to the plate of another capacitor, which is positively charged. On fig. 3 shows an example of series connection of capacitors.
Rice. 3. Series connection of two capacitors
With this type of connection, the following rule applies: the reciprocal of the capacitance of the capacitor bank in series connection is equal to the sum of the reciprocals of the capacitances of the individual capacitors. Therefore:
1/C = 1/C1 + 1/C2 + 1/C3 + ...
With this type of connection, the capacitance of the capacitor bank is less than the capacitance of any of the capacitors.
Parallel connection. When capacitors are connected in parallel, positively charged plates are connected to positively charged ones, and negatively charged ones to negative ones (Fig. 4).
Rice. 4. Parallel connection of two capacitors
In this case, the capacitance of the capacitor bank will be equal to the sum of the electrical capacitances of the capacitors:
C = C1 + C2 + C3 + ...

The existence of an entropy rule for quantum entanglement has been proven
09.05.2024
Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Energy from space for Starship
08.05.2024
Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>
| Random news from the Archive Nanobots for the treatment of astronauts
01.02.2018
The UAE Ministry of Health has announced plans to build the world's first hospital in space.
The project will become part of the UAE national space program. "Astronauts will be provided with medical treatment in space, but it will be controlled on Earth with the help of nanotechnology," UAE Ministry of Health spokeswoman Dr. Kulthum al-Belushi said.
The project will be launched along with the start of the UAE mission to Mars in 2020. First, the hospital project will be tested on Earth.
According to Thierry Karim Luess, head of the medical company Fractal Systems, which received government permission to develop a medical program for the planned Martian mission, before launch, Arab astronauts will be injected into the bloodstream with nanorobots that will repair or remove damaged body cells. The statement also mentioned plans for the use of artificial intelligence.
