Yadda za a kula cewa kan darajar da elektronu ke tafi daga wata zuwa wata a cikin hanyar?

Yanzu da mutanen electrons da ke jin kasa a cikin wire a cikin circuit zai iya tabbatar da ita daga ma'adin current. Current tana masu amfani a kan amperes (Ampere, A), wanda aka bayyana shi ne 1 Coulomb (C) da take jin kasa a cikin wire a baya da kasa. Na sani cewa charge na 1 coulomb ya kai kusan 6.242 x 10^18 electrons.

Tsarin haishe

• Current (I) : Current tana masu amfani a kan amperes (A) kuma yana nufin yadda charge take jin kasa a cikin wire a baya da kasa.

• Jumlah electrons (N) : Jumlah electrons da ke jin kasa a cikin wire a baya da kasa.

Tsarin ya kai:

• N= (I x t) /qe

• I shine current (unit: ampere, A)

• t shine time (a baya da kasa, s), kuma a wannan haishe t=1 second

• qe shine charge na electron guda (unit: coulomb, C), qe≈1.602×10−19 coulomb

Tsarin da ya fi sanarwa:

N = I / 1.602 x 10-19

Amfani da ita a cikin circuits na gaba-gaba

• Bayyana current: Karkashin da ya ba a yi shine amfani da Ammeter don bayyana ma'adinito da ke jin kasa a cikin circuit.

• Bayyana time: A wannan misal, muna set time t=1 second, amma idan muna bukata bayyana jumlah electrons a wasu lokaci, muna bukata tsari da time value a cikin haka.

• Haishe jumlah electrons: Ma'adinito da aka bayyana tana amfani a cikin tsarin da aka bayyana don haishe jumlah electrons da ke jin kasa a cikin wire a baya da kasa.

Misal na amfani

Idan muna bukata haishe jumlah electrons a cikin circuit na gaba-gaba da current na 2 amps (I = 2 A), kuma:

N=2/1.602×10⁻¹⁹≈1.248×10¹⁹

Wannan yana nufin cewa a current na 2 amps, kusan 1.248 × 10^19 electrons ce da ke jin kasa a cikin wire a baya da kasa.

Abubuwan da suka bukata

• Gaskiya: Zai iya kasance abubuwa a cikin bayyanin gaba-gaba, saboda haka, darajar da aka haishe zai iya kasance tare da rarrabe.

• Temperature da material: Yawan temperature da material na wire zai iya haɗa da zama da efficiency na current, wanda zai iya haɗa da darajinsa da aka haishe.

• Fasahohin electrons: zai iya kasance fasahohin electrons a cikin circuit na gaba-gaba, saboda haka, total da electrons zai iya haɗa da wannan abubuwa.

Daga tsarin da abubuwan da aka bayyana, za a iya haishe jumlah electrons da ke jin kasa a cikin wire a baya da kasa. Wannan yana nufin cewa muna samun fahimta game da strength na current da flow na electrons a cikin circuits.
