Mai suna Drift Velocity?

An gama da suka tsaya ce ta ake kira da yawan zafi mai yawa a kan abu da ya yi nasararsa a kan tushen kadan da ke gudanar. Wannan bayani ana iya haɗa da elektronon da suka fito a kan conductor. Tattaunawa, elektronon da suka fito suna yi nasararsa a kan conductor da yawa mai yawa da kuma tushen kadan. Idan an yi electric field a cikin conductor, elektronon da suka fito suna samun hukuma na farko da tushen electric field.

Amma, wannan electric field ba ya ƙara nasararsa mai yawa da elektronon da suka fito. Ba tare, ya sauya su zuwa masu potenshi mai yawa ne da aka baka a kan conductor. Saboda haka, elektronon suna yi nasararsa a kan masu potenshi mai yawa a kan conductor da yawa mai yawa.

Wannan ya ƙarfin da elektronon da suka fito suka samun yawan zafi mai yawa zuwa masu potenshi mai yawa a kan conductor, wanda ake kiran ta a matsayin drift velocity da elektronon.

Karin electrical current, saboda drift velocity da elektronon a kan conductor da aka baka electric field, ake kiran ta a matsayin drift current. Yana da kyau a lura cewa duka electrical current na da muhimmanci drift current.

The Relationship between Drift Velocity and Electron Mobility

Amsa ma a duba waɗanda suka fito a kan abu mai sani, kamar metal, a kan yawan jiki. A nan akwai da elektronon da suka fito. A tarihin ilimi, abu mai sani, idan ya shahara, ya kamata a canza da elektronon da suka fito a kan yawan jiki mai yawa da absolute zero.

Elektronon da suka fito a kan conductor suna yi nasararsa mai yawa, da suka dole da atoms masu yawan jiki da suka kawo nasararsa.

Idan an yi electric field a kan conductor, elektronon suna ji zuwa terminali mai yawa na voltage, wanda ake kiran ta a matsayin voltage. Amma, nasararsa da elektronon suka yi, ba a cikin lurfi ba.

A lokacin da elektronon suka ji zuwa terminali mai yawa, suna dole da atoms da suka kawo nasararsa. Duk da ita, suna samun karshen kinetic energy, wadanda suka ciyar da su saboda electric field, don su ji zuwa terminali mai yawa.

Duk da ita, suna samun karshen kinetic energy, wadanda suka ciyar da su saboda electric field, don su ji zuwa terminali mai yawa. Saboda haka, electric field ba ya ƙara nasararsa mai yawa da elektronon, amma ya sauya su zuwa terminali mai yawa.

A cikin kalmar, electric field ya sauya elektronon zuwa terminali mai yawa, don su samun drift velocity. Idan intenciti na electric field ya ƙara, elektronon suna ji zuwa terminali mai yawa da yawa mai yawa. Saboda haka, elektronon suna samun drift velocity mai yawa zuwa terminali mai yawa, ko kuma a kan yadda electric field ya ƙara.

A nan, idan ν yana nufin drift velocity da E yana nufin electric field, electron mobility, wanda ake kiran ta a matsayin μe, yana iya a bayyana a matsayin ratio na ν zuwa E.

A nan, μe yana nufin electron mobility.

Drift Velocity, Drift Current, and Electron Mobility: An Animation

Tsunawa da elektronon, saboda drift velocity, ya ƙarfin drift current.

Na fahimtar da ingantaccen bayani, mafahimtoci da drift velocity, drift current, da electron mobility suka samun muhimman ruwa a kan duniya da elektronon da physics.

Karin drift current, wanda ake kiran ta a matsayin drift current, yana ƙarfin da elektronon suka yi saboda drift velocity.
