1.	Give me answer fastWhat are the factors on which resistance o A wire of length 1 and resistance 'R' is stretched to get the radius of cross-section halved. What is the new resistance of the wire after stretching?
Answer» Explanation: Length (l) is doubled & AREA of cross SECTION (A) is halved. l BECOMES 2l & A becomes 2 A R=P A L now take l=2l,A= 2 A R= A/2 P2l =4P A L ⇒4R Resistance becomes 4 times 1) RESISTIVITY does not depend on its length 02 Area. Hence, it does not change

Answer»

Explanation:

Length (l) is doubled & AREA of cross SECTION (A) is halved.

l BECOMES 2l & A becomes

R=P

now take l=2l,A=

A/2

P2l

=4P

⇒4R

Resistance becomes 4 times

1) RESISTIVITY does not depend on its length 02 Area.

Hence, it does not change
