Resistivity and Factors of Resistance || in Hindi for Class 10

In this Physics video for Class 10 in Hindi we explained what resistivity of a material is and what are the factors of resistance of a conductor. This is a topic of Chapter 12 - 'Electricity' from NCERT for Class 10.
Electrical resistivity is a fundamental property of a material that measures how strongly it resists electric current.
Electrical resistivity of a material is defined as the resistance offered by a slab of unit length and unit cross sectional area made by that material.
SI unit of resistance is ohm - meter (Ω-m)
Different factors of resistance are -
(1) Material
(2) Length
(3) Cross-sectional Area
(4) Temperature

Sir ek request ye hai ki please ek baar is topic pr video bana dijiye jo ki related hai conventional current aur electronic current pr 1.Sir kyu conventional current ko ye naam diya jata hai 2.sir wo kaun se kuchh laws electricity se related hai ki jinki validity ko banaye rkhne ki wajah se hame conventional current ko prefer krna padta hai. 3.sir ek cell ki help se thoda samjha dijiye ki kaunsa end high potential pe hota hai aur kaun sa low pr aur 4.sir positive end ko kyu high potential pr mana jata hai jabki high potential pr to negative end hota hai jiski wajah se electron move krte hai aur current banta hai Please sir ek detailed video conventional current aur electronic current pr bana dijiye 🙏

What is the difference between resistance and resistivity?

[@karranveersingh6]

Resistance and resistivity are related but distinct concepts in electrical circuits: 1. **Resistance (R)**: This is a measure of how much a material or component opposes the flow of electric current. It depends on the material, its dimensions, and its temperature. Resistance is measured in ohms (Ω). For a given material, resistance increases with length and decreases with cross-sectional area. The formula is: \[ R = \frac{V}{I} \] where \( V \) is the voltage across the component and \( I \) is the current flowing through it. 2. **Resistivity (ρ)**: This is a fundamental property of a material that quantifies how strongly the material resists electrical current flow. It is an intrinsic property and is measured in ohm-meters (Ω·m). Resistivity is independent of the size and shape of the material. The formula relating resistivity to resistance is: \[ R = \frac{ρL}{A} \] where \( L \) is the length of the material, \( A \) is the cross-sectional area, and \( ρ \) is the resistivity. In summary, resistivity is a property of the material itself, while resistance depends on both the material and the physical dimensions of the object made from that material.

I was Waiting For This Quality Concept🤪

Just when i think physics is not my thing, gods makes me stumble across your videos😩💯

Sir, agar resistances ko parallel me connect karne par unka Voltage same hota hai toh un dono ke beech current kaise flow karta hai. Please batado sir🙏🙏🙏

[@edupoint.secondary]

Kya Satwik !!! Dil tod dete ho yaar!!! Same voltage matlab same potential difference.

Very good video sir I really appreciate your potential 😊

[@SahilSingh-cb7us]

Sir resistivity kya resistance ki tarah current ko oppose karta h And sir resistivity means resistance for 1m and 1m square length and cross sectional area

[@BHATFUNTV]

Sir as we know that due to potential difference there is current in a circuit i.e I depends on V how we can say that V is proportional to I which means due to current there is potential difference

[@RAJPUT-bn3zm]

Proportion means if the potential difference increase then the current is also increase means the no of electron passes more through a cross section.😁😀

[@RAJPUT-bn3zm]

Current ki bajah se potential difference nhi potential difference create krne ki bajah se current flow krta hai🙂🙂

Sir ek baat puchna thaa ki cell negetive terminal pe potential kuch ho aur positive pe kuch ye potential differnce kabhi khatam nahi hota hai kya jaise do tank ek samay pe akar pani se balance ho jata hai Plz reply sir

Sir then why all people says that the registence is the opposition of the flow of charge in the whole derivatives of the registence we cannot see any connection between registence and opposition

I is directly proportional to v because if potential difference increases then current increases but if we not connect to cell then potential difference will increase but current will not icrease
