Employment munda magetsi pa mlandu kusamutsidwa

Pa mlandu uliwonse kuti mukusungira magetsi mphamvu wakumunda anagwira. Pa nkhani imeneyi, kayendedwe ka mlandu m'munda ndi chimafotokozera ntchito m'munda magetsi. Kodi kuwerengera ntchito imeneyi?

Ntchito m'munda magetsi ndi electrocharge kusamuka pamodzi wochititsa lapansi. Zidzakhala wofanana ndi mankhwala a voteji, panopa ndi nthawi imene ntchito.

Kugwiritsa ntchito njira Chilamulo Ohm, titha kupeza ochepa options osiyana a chilinganizo cha mawerengedwe a ntchito panopa:

A = U˖I˖t = I²R˖t = (U² / R) T.

Malinga ndi kusamala mphamvu malamulo machitidwe a mphamvu za magetsi kumunda ndi wofanana ndi kusintha kwa gawo limodzi unyolo, ndipo chotero mphamvu anamasulidwa ndi wochititsa, adzakhala wofanana pano.

Timasonyeza mu dongosolo SI:

[A] = V˖A˖s = Vt˖s J =

1 kVt˖chas J = 3600000.

Zatsopano ankachiritsa. Taganizirani kayendedwe ka woyang'anira mu munda womwewo, amene anapanga ndi awiri spaced kufanana mbale A ndi B ndi mlandu milandu zosiyana. M'munda mizere ya mphamvu mu m'litali perpendicular kwa mbale izi, ndi pamene mbale A ndithu mlandu, ndiye wakumunda mphamvu E imatsogoleredwa kuchokera A kuti B.

Kuganiza kuti zabwino mlandu Q anasamuka ku mfundo kufika b pamodzi ndi njira umasinthasintha AB = m.

Popeza mphamvu kuti amachita pa mlandu umene kusungidwa mu munda adzakhala wofanana F = qE, ntchito anachita pa kayendedwe ka mlandu m'munda malinga ndi njira anakonzeratu chimafotokozera aone kuti pali kuti:

A = FS Ko α, kapena A = qFs Ko α.

Koma m Ko α = D, kumene anthu d - mtunda pakati pa zipangizo.

Ndizoonekeratu: A = qEd.

Tiyeni tsopano kusuntha mlandu Q wa ndi b Ndipotu acb. Ntchito m'munda magetsi yociticka m'njira imeneyi, ndi Uwerenge ntchito m'madera ena kuti: Mac = s₁, CB = s₂, mwachitsanzo

A = qEs₁ Ko α₁ + qEs₂ Ko α₂,

A = qE (s₁ Ko α₁ + s₂ Ko α₂,).

Koma s₁ Ko α₁ + s₂ Ko α₂ = D, motero Pankhaniyi A = qEd.

Komanso, kuganiza kuti chimachititsanso mlandu Q kuchokera kwa b ndi pamapindikira umasinthasintha. Kuwerengetsa ntchito pa njira iyi yokhota kumapeto, m'pofunika delaminate m'munda pakati pa mbale A ndi kuchuluka kwa ndege kufanana amene ali pafupi wina ndi mnzake kuti zigawo munthu wa njira m pakati pa ndege tinganene kuti molunjika.

Pankhaniyi, ntchito m'minda magetsi kwaiye pa aliyense wa zigawo deta njira adzakhala A₁ = qEd₁, kumene d₁ - mtunda pakati pa ndege zoyandikana. A ntchito kotheratu njira yonse D adzakhala wofanana ndi mankhwala Uwerenge d₁ qE ndi mtunda wofanana d. Choncho, chifukwa cha njira yokhota kumapeto adzakhala wofanana ntchito A = qEd.

Zitsanzo kuonedwa ndi ife, amasonyeza kuti ntchito m'munda magetsi pa gulu mlandu kwa mfundo iriyonse kwa wina zimadalira pa mawonekedwe a njira ya kayendedwe, komanso zimatengera chokhazikika pa mfundo malo deta m'munda.

Komanso tikudziwa kuti ntchito imene anachita ndi yokoka pamene thupi ikuyenda pa ndege okonda ndi kutalika L, adzakhala ofanana pa ntchito imene imapangitsa thupi pamene zakugwa kutalika H, ndi kutalika kwa ndege otsamira. Choncho, ntchito ya mphamvu yokoka kapena, makamaka, ntchito ya kusuntha thupi pamene m'munda yokoka, nayenso sikudalira pa mawonekedwe a m'njira zimatengera yekha pa kusiyana pa zitunda za mfundo loyamba ndi lomaliza la njira.

Choncho n'zotheka kutsimikizira kuti zimenezi chuma chofunika mwina ali ndi yunifolomu, komanso munda onse magetsi. Similar ndi choona cha mphamvu yokoka.

Opaleshoni munda electrostatic kwa chokwawa mtengo kuchokera nthawi ina kuti mfundo ina anatsimikiza ndi liniya yofunika:

A₁₂ = ∫ L₁₂q (Edl),

kumene L₁₂ - ndi njira yodutsamo a mlandu, DL - ndi n'zochepa kusamutsidwa pamodzi njira yodutsamo lapansi. Ngati dera chatsekedwa, ndiye chizindikiro yofunika ntchito ∫; Pankhaniyi amaganiza kuti osankhidwa malangizo kulambalala dera.

Ntchito electrostatic mphamvu sikudalira pa mawonekedwe a njira, koma pa ndondomeko ya mfundo loyamba ndi lomaliza la kusamutsidwa. Choncho, mphamvu kumunda ndiwofatsa, ndi m'munda palokha - zingakhale. Dziwani kuti ntchito iliyonse mphamvu ndiwofatsa pamodzi njira chatsekedwa ndi ziro.
