1.Three copper wires have their lengths in the ratio5:3:1 and their masses are in the ratio 1:35. Their electrical resistance will be in the ratiopls with explanation |
|
Answer» I PROMISE I WILL FOLLOW YOU IF YOU MARK AS BRAINLIST THANKS FOR QUESTION
YOUR ANSWER IS Resistance of a WIRE is given as A ρL
This is the same as A×L ρL
= V ρL 2
So, resistance is proportional to M L 2
The RATIO of resistances is, 1 25
: 3 9
: 5 1
=125:15:1 |
