Factors Determining Resistance

can you give a detailed explanation on formulae  r=p l/a i need the answer quickly before 02:00

Asked by Anirudh 4th February 2018 11:11 AM

Which one will have more reactivity,a sphere with radius 1 or a cube of length 1 unit?

Q . What is likely to happen and it would effect the value of resistance passing the current for a longer time ?

Asked by sucharitasahoo1 15th March 2018 3:16 AM

what happens to the resistance of a conductor when (a) length is doubled  (b) area is doubled (c) length doubled and area is halved  (d) radius is doubled (e) diameteris doubled

How solve problems related to resistance

Asked by randhirsingh 1st January 2019 6:36 PM

How will the resistance change if the length of the wire is doubled?

Asked by ms0851000 11th March 2019 6:55 PM

How will the resistance of a wire change if the area of cross section of wire is increased to 3 times?

WHAT IS THE RELEATIONSHIP BETWEEN RESISTANCE AND RESISTIVITY?

Asked by punithanrr18 13th March 2019 11:15 PM

Explain it with reasons plz

Asked by vishakhachandan026 1st April 2019 8:31 AM

a given length of a wire is doubled of itself and this process is repeated once again. by what factor does the resistence of the wire changes

Asked by ajayrath7 4th April 2019 7:44 PM

two wires of same material has length in ratio 1:2. If the difference in their series and parallel equivalent is 21 ohm then calculate the resistances of the wire.

Asked by Aritra 16th April 2019 11:43 PM

What gauge wire should I use?                        Nichrome or kanthal?                                      ​​​​​​​​​​​​​​​​​​​​​whose resistance vary to temperatura and how much?

Asked by rohitshorya 15th July 2020 8:03 PM

at what temperature would the resistance of a copper wire be double its resistance at zero degree celsius if Alpha is equals to 1 by 273 degree Celsius inverse

Asked by singhnatasha79551 20th March 2021 10:50 AM

calculate the resistance of 1km long copper wire of radius 1mm
