The simba electric munda

Kutaura chii simba electric munda, zvinokosha kutaura kuti zviri parameters zvinokosha. Pasinei chokwadi kuti shoko rokuti "simba" pacharo rakanyatsojeka vanoshamwaridzana uye, panguva Pakutanga, pachena, muchiitiko ichi, iwe unofanira kunzwisisa zviri pangozi rakanaka. Somuenzaniso, sezvo chikazozikamwa, simba electric munda kuyerwa chero zvemasanga pamwero kwayo, conventionally sokugamuchira mavambo (ndiko kuti, razero). Kunyange zvazvo izvi zvinopa zvimwe kuchinja pakugadzirira Masvomhu, kukanganisa kungaita kuti akasiyana chaizvo kadambari simba. Pari ticharamba kujekesa gare gare, achishandisa nzira.

The simba electric munda akarondedzera kukurukurirana pfungwa mhosva maviri kana kupfuura zvakananga. Chimbofunga mhosva mbiri - q1 uye q2. The zvinogona nesimba yemagetsi munda (mu iyi - electrostatics) richinzi:

W = (1/4 * Pi * E0) / (q1 * q2 / R),

apo E0 - makakatanwa, R - kure pakati mhosva, Pi - 3,141.

Sezvo rokutanga munda anoita wechipiri (ndiEzekieri), ipapo minda izvi havatsananguri potentials. Kutanga, vakapomera ane zvainoita rechipiri:

W = 0.5 * (q1 * Fi1 + q2 * Fi2).

In mutoo uyu (runotaurwa 1), pane tsika itsva mbiri - Fi1 uye Fi2. We compute navo.

Fi1 = (1/4 * Pi * E0) / (q2 / R).

Naizvozvo:

Fi2 = (1/4 * Pi * E0) / (q1 / R).

Zvino wekutanga inokosha ndiko payakavakirwa "1" rine mazwi maviri (Q * Fi), chaizvoizvo rinomirira kukurukurirana simba uye mutariri chinokonzera kuti 0.5. Zvisinei, simba electric munda - hakusi chikamu chipi muripo, naizvozvo, kuti kutora nhoroondo iyi inoti, zvinokosha kuti ataure kururamiswa, "0.5".

Sezvambotaurwa, kubata pane mumwe mhosva dzakawanda (mbiri kwete chete). Panyaya iyi, simba arambe achirema electric munda kumusoro. kukosha kwayo anogona kuwanikwa Achipfupikisa kutengwa nokuda peya nerimwe mashoko.

Zvino shure nenhau kusarudza nezvezvinotaurwa ataurwa pakutanga kwenyaya ino. Saka, kubva Masvomhu, zvinoreva kuti kana dzemaitirwe rinoitwa pomudzimai zvemasanga pfungwa, daro kubva kupomerwa zvinova zvinowanzoita kuti kusaverengeka, zvinoguma kukosha kwebasa, rakamwisa munda, mhosva zvakasiyana mumwe ari isingaperi kure. Asi kana zvakakodzera kuziva kukosha mumunda basa kuitwa mune duku kwebasa mhosva pachavo, bhuku pfungwa anogona kusarudzwa kana, sezvo zvichiita ukoshi kukarukureta ndiyo yakazvimirira kusarudza nezvezvinotaurwa pfungwa.

Heuno muenzaniso, sezvo rinogona kushandiswa zvinobatsira Masvomhu. Somuenzaniso, kune vatatu mhosva, ivo spatial configuration chiri netriangle. Distance (R) pakati q1, q2 uye q3 vakaenzana.

We ngaaverenge zvinogona:

Fi = 2 * (Q / 4 * Pi * E0 * R).

zvino tinogona kuona kubata simba mirairo pachavo:

W0 = 3 * ((Q * Q) / 4 * 3,141 * E0 * R).

Iri ndiro basa kuti vachaitwa kana uchifamba isingaperi kure.

Kana misha yose mitatu rinobva vanhuwo muzinda zvakaenzana, kuti Triangle aumba mativi r1 (pamusoro yapfuura R).

Kuona simba:

W = 3 * ((Q * q) / 4 * Pi * E0 * r1).

Muchiitiko chino, tinogona kutaura mukuderedza zvachose simba kukosha yose ezvinhu mhosva matatu. Zvinofanira kucherechedzwa kuti kana kukosha r1 (R) uderedze kusaverengeka, kwokutanga simba uye basa ikabereka vakaenzana.

Omesa basa, uye bvisa kubva ezvinhu ane asingashumbi mutariri. Zvinoguma chaiwo nyaya mhosva mbiri riri kure r.

The simba kwegadziriro kwakadaro akaenzana:

W = (Q * q) / (4 * Pi * E0 * R).

A bhokisi achaita basa racho pacharo, iro dziwande kuenzana:

A = 2 * ((Q * q) / 4 * Pi * E0 * R).

Zvadaro zvose anongoti: kubvisa imwe mutariri kuchaguma kuti yose simba akaenzana razero (hapana Clearance). Panyaya iyi, basa uye munda dziwande equalized. Nemamwe mashoko, chepakutanga simba iri dzikwanise basa zvachose.

Masvomhu chokuita nokutsunga simba nokuda yemagetsi munda aiwanzoshandiswa kugadzira kusarudzwa capacitors. Pashure mudziyo mumwe akadaro ine ndiro mbiri dzakaparadzaniswa kure R, panguva imwe neimwe mhosva iri kuramba.
