Definition of the parallel plate capacitor

The parallel plate capacitor is a capacitor that consists of two parallel conductor plates, each plate having an equal cross-sectional area (A) and two plates separated by a certain distance (d), as shown in the figure left. One of the conductor plates is positively charged (+Q) while the other conductor plate is negatively charged (-Q), where the amount of kharash koronto on each plate is equal. So that the charge does not move to the air molecule, the capacitor is isolated from the environment, and between the two plates, there is a vacuum.

Wali ma xasuusataa xusuusta markii ugu horreysay ee aad baabuur raacday? Markaad baabuur socoto, waxaad u aragtaa sidii geed ama dhisme dhaqaaqaya. Waqtigaas, waxaa laga yaabaa inaad u malaynayso in geedaha ama dhismayaashu ay dhaqaaqayaan, inta adiga iyo baabuurku aad nasanaysaan. Xaqiiqdii, adiga iyo gaadhiguba way dhaqaaqaan, halka geedaha ama dhismayaashuna ay nasanayaan. Khibraddan dhaqdhaqaaqa been abuurka ah ayaa dhab ahaantii la kulmaa maalin kasta. Subax kasta, "qorraxdu" waxay ka soo baxdaa geeska bari ka dibna waxay u dhaqaaqdaa galbeed oo waxay "dhacdaa" geeska galbeed galabtii.

Sidoo kale, habeenkii, waxaad inta badan aragtaa dayaxa oo ka wareegaya bari ilaa galbeed. Ma waligaa ma ka fikirtay ama ma qiyaastay in qorraxda iyo dayaxu ay ku wareegayaan dhulka, halka dhulku uu nastay?

Dib u eeg shay wareegaya, sida albaabka qol. Marka albaabku furmo ama la xidho, albaabku wuu wareegayaa. Xidhmooyinka albaabka ku xidha derbiga ayaa u shaqeeya sidii dhidibka wareegga.

Sawirka albaabka waxaa laga arkayaa kor. Dib u eeg tusaale meesha albaabka lagu riixayo laba xoog oo isku mid ah oo leh baaxad iyo jiha isku mid ah, halkaas oo jihada xooggu ay ku toosan tahay albaabka. Marka hore, albaabka waxaa lagu riixaa xoog F ah.₁, r₁ laga bilaabo dhidibka wareegga. Dabadeed, albaabka waxaa lagu riixaa xoogga F₂, r₂ meel ka fog dhidibka wareegga. Inkastoo baaxadda iyo jihada xoogga F₁ =F₂, xoogga F₂ waxay sababtaa in albaabku si dhakhso ah u wareego marka loo eego xoogga F₁Si kale haddii loo dhigo, xoogga F₂ waxay sababtaa dardargelin xagal oo weyn marka loo eego xoogga F₁Waad caddeyn kartaa tan.

4.1 The relationship between the moment of force, the moment of inertia, and the angular acceleration

If there is a resultant force (ΣF) acting on an object with mass (m) then the object moves linearly with a certain acceleration (a). The relationship between the resultant force, mass, and dardargelinta is expressed by the equation:

ΣF = ma

This is the equation of Newton‘s second law.

The quantities of the rotational motion which are identical to the resultant force (ΣF) in linear motion is the resultant moment of force (Στ). The quantities of the rotational motion that are identical to mass (m) in linear motion is the moment of inertia (I). The quantities of the rotational motion that are identical to acceleration (a) in linear motion is the angular acceleration (α).

1. Definition of the xarunta culeyska

A rigid body is composed of many particles; therefore, the gravitational force acting on each of these particles. In other words, each particle has its weight. The center of gravity of an object is a point on the object where the weight of all parts of the object is considered to be centered at that point.

Article about the Types of equilibrium of the rigid body

Not all things we find in everyday life always rest. Maybe at first the object rest, but if it is moved (for example by the wind) objects can move. The problem is, whether after moving, objects return to their original position or not. This depends on the type of balance of the object. After moving, there will be three possibilities, namely:

(1) the object returns to its original position,

(2) the object moves away from its original position,

(3) the object remains in its new position.

1. Shuruudda koowaad

Sharciga Labaad ee Newton wuxuu sheegayaa haddii xoogga ka dhasha shay (shay loo arko inuu yahay hal walax) uusan eber ahayn,

markaas shaygu wuxuu ku dhaqaaqi doonaa xawaare joogto ah, halkaas oo jihada dhaqdhaqaaqa shayga = jihada xoogga guud. Haddii xoogga ka dhasha uu eber yahay, markaas shaygu wuxuu ku nasanayaa ama wuxuu ku socdaa xawaare joogto ah.

ΣF = ma

Marka shay uu nasto ama uu ku socdo xawaare joogto ah, shaygu ma laha dardargelin (a). Sababtoo ah dardargelinta (a) = 0, isla'egta kore waxay isu beddeshaa:

1. Hooke’s law for springs

If the spring is pulled to the right, the spring will stretch and increase in length (figure 1). If the pull force is not huge, it is found that the increase in spring length (Δx) is proportional to the magnitude of the pull force (F). In other words, the greater the pull force, the greater the length of the spring. Comparison of the magnitude of the pull force (F) and the increase in the spring length (Δx) is constant.
