Paschen's law is an equation that gives the breakdown voltage, that is, the voltage necessary to start a discharge or electric arc, between two electrodes in a gas as a function of pressure and gap length. [2] [3] It is named after Friedrich Paschen who discovered it empirically in 1889. [4]
Louis Carl Heinrich Friedrich Paschen (22 January 1865 – 25 February 1947) was a German physicist, known for his work on electrical discharges. He is also known for the Paschen series , a series of hydrogen spectral lines in the infrared region that he first observed in 1908.
Servicing a Hydrogen Car. Like electric cars, hydrogen vehicles require dealership service centers to exercise some special precautions. HFCVs have the same high-voltage battery packs as a hybrid ...
That's the hydrogen fuel-cell vehicle, related to an EV but with specific differences that make hydrogen cars different and much rarer. To date, about 2.5 million EVs have been sold in the U.S.
The firm conducts programs designed to test for safety, energy, fuel economy, emissions, durability, noise, crash, crash simulation and performance. It tests trucks, buses, recreational vehicles, motorcycles, electric vehicles, passenger cars and components. Brett Roubinek has been president and CEO of TRC Inc. since January 2018. [3]
For example, the 2 → 1 line is called "Lyman-alpha" (Ly-α), while the 7 → 3 line is called "Paschen-delta" (Pa-δ). Energy level diagram of electrons in hydrogen atom. There are emission lines from hydrogen that fall outside of these series, such as the 21 cm line.
You've probably heard of fuel cell cars. They use hydrogen gas to make electricity to power a motor that drives the car. The waste product: water vapor. The technology is clean, ...
