emission current उदाहरण वाक्य
उदाहरण वाक्य
अधिक: आगे- In this case, the electron gun acceleration potential limits the emission current.
- After flashing the emission current is high but unstable.
- The emission current density " J " varies from position to position across the emitter surface.
- In this case, the emission current is regulated by the thermionic emission process, given by the Richardson Dushman equation.
- The thermionic emission current density, J, rises rapidly with increasing temperature, releasing a significant number of electrons into the vacuum near the surface.
- The emission current as given above is many times greater than that normally collected by the electrodes, except in some pulsed valves such as the cavity magnetron.
- The total emission current " i " from a defined part of the emitter is obtained by integrating " J " across this part.
- In 1926, Rother, using a still newer platform galvanometer of sensitivity 26 pA, measured the field emission currents in a " hard " vacuum between closely spaced electrodes.
- The solution was to add another grid between the screen grid and the main anode, called the suppressor grid ( since it suppressed secondary emission current toward the screen grid ).
- For practical emitters, the emission current density used in Fowler-Nordheim-type equations is always the current density at some reference point ( though this is usually not stated ).
