What is Resistance? Causes of Resistance? Resistance increases with length and decreases with area of conductor.
The electrical resistance of an object is a measure of its opposition to the flow of electric current. Electrical resistance shares some conceptual parallels with the notion of mechanical friction.
We find that it is a property of the material. It depends on the dimensions of the material too:
• Doubling length of a conductor doubles resistance too. In general, resistance is proportional to length. AND
• Halving area of the cross-section of a conductor doubles resistance too. In general, resistance is inversely proportional to cross-sectional area.

aap mahan hain, koyi bhi hard cheez ko badi aasani se samjha dete hain...feel proud to be your student.

@mohammadarif2258 6 лет назад

Light bulb (B) will produce more light because filament of the bulb has less cross sectional area therefore it shows more resistance to the flow of current, as a result collision of electrons will increased, hence kinetic energy of the electrons will convert into thermal energy which results in more production of light...

but power=i^2 R direct relationship

@goldensiddiqui 3 года назад

'B' wala jyda roshni paida krega , because B ptla hai , means uska Area kam hai so for given condition wo jyda resistance offer krega and utna jyda energy waste krega , jitna energy waste wo energy heat and and light ke form me hame dikhega ..

@hirokjyotiroy9675 6 лет назад

The answer is B. By the way sir, you are a great teacher. Your examples are totally different from other people but one can directly relate it with the main theory.

@fitnessfreak8788 6 лет назад

Sir, option (b) Will give more light because the resistivity will increase and the filament will become more warmer then option (a)

@premshankar9018 6 лет назад

You r the best sir. Salute u . Sir naam kya change kar diya…? Pahle wala jyada attractive tha.

@prasidsandave8624 5 лет назад

Bulb B will produce more light as it's cross sectional area is less hence it has more resistance as compared to bulb A . Please reply that my answer is right or not.

sir jo copper wire hota hai agar usme copper ki jagah silver use kre to kya hoga plz tell me

@yugalkishore8991 7 лет назад

Answer is bulb B because bulb ke filament me RESISTANCE increase karne se HEAT hoga jisse jya LIGHT jyada produce hogi. SIR PLEASE REPLY IF I AM RIGHT

@drmsgfans 7 лет назад

great concepts sir 👌👌👍 sir series and parallels circuits dekhna sikha do plz 🙏 dimag khrab kr rkha hai inhone..

@bhoopeshshishodia9837 6 лет назад

Sir option A will glow more as you told us that area is inversely proportinate to resistence ,which means that the resistence will be less and more current will pass through it......

@ishanbansal4099 5 лет назад

But, if there is less resistance there will be lesser heat produced. Therefore, bulb A will have lesser resistance as compared to bulb B. However, bulb B will be brighter than bulb A.

@arshdeepsinghsidhu3228 5 лет назад

@electricallearner 6 лет назад

@ManishKumar-em6qc 6 лет назад

Bulb A glow more then bulb B , because bulb A offer less resistance then bulb B, Am I right or wrong sir.

@ubaidurrehman6955 4 года назад

You r best teacher

@shivshambhuchoudhary9087 7 лет назад

bulb with thicker filamnt, since, r decreases due to increase in A,so more current willl flow and hence brighter

@prasanjeet5125 7 лет назад

Sir i think patli vali jyada glow kregi because usme resistance zada h or jisme resistance jyada hota h vo jyada heat krti h

@gauravpatil759 6 лет назад

Aur agar current kam nahi hoga to resistor ka kya use kuki resistor lagane ke bad bhi utana hi current pass hoga

@adityasaini3792 6 лет назад

Sir jiski filament thin hai kyu ki sir area kam hone par resistance jyada hoga or dhara ke raste me rukavat hogi to vo jyda heat genrate karega or jyada shining karega

@sahilyadao 7 лет назад

Can you add some numericals based on resistance? It will be more better then to understand!

@AbbasAli-js7me 6 лет назад

sir what is means by one ohm

@kumar_mandeep 7 лет назад

sir , apne is video ki starting me ohm law btate hue likha ki voltage directly proportional to current but sir current directly proportional to voltage kehne ka to koi mean nhi bnta na..?? becoz jb hm voltage increase krenge tbhi current increase hoga na

@ashieshkapoor 7 лет назад

u right. but as i said k is constant and 1/k is constant too. people prefererd to write it like that :(

@ravisiddhartha4518 6 лет назад

Sir ohm s law ac DC and semiconductor apply Kar sakte h

@rahulkr1842 7 лет назад

since from the video humne dekha ki area of crosssection ko kum karenge toh resistance badhega. toh ressistance ke badhne ke karan thin wire jaada heat hogi or heat ke karan light jaada aayega......please reply me sir i am right or wrong .me sahi ki galat hoon?

@adarshsasidharan254 7 лет назад

Rahul Kr bhai sai he tu

@muktikantabaral4278 6 лет назад

Haan bhai bilkul thick

@sarthakkumar7981 5 лет назад

bulb with filament having less cross section area will produce more light because the cross section area being less the heat energy produced will be more because of the excessive collision of electrons.

@abnomikhan2211 4 года назад

V=IR mein R ksy constant rahy ga jb current pass ho ga Temperature increase kry ga so Resistance chances

@naushadalisurve2035 5 лет назад

@vikashkumarbasant8632 7 лет назад

@pankajjoshi8428 6 лет назад

sir,because both bulbs are made from your special hands....so both will glow brighter compared to the other bulbs in this world.

@kumar_mandeep 7 лет назад

because cross section area jyada h 'A' ka as compare to 'B' then resistance km hoga then current jyada flow krega then itensity of light increases

@Dolly6746 6 лет назад

Option b is right......because Power =i square. R Jiska filament patlaa hai uskaa power jyaadaa hoga. Yani jyada Watt ka bulb hoga...to jada glow krega

thin wire corresponds to more resistance so more power will be consumed. Hence, second will glow brighter than the latter one.
