Question

a current of 2A is drawn by a wire. if the length of the wire is double then the amount of current drawn by the wire would be​

Answer 1

We know  

R=ρ  

A

l

​  

 , now area becomes half and length is double .

R  

1

​  

=ρ  

2

A

​  

 

2l

​  

=ρ  

A

4l

​  

=4R

please mark me as brainliest

Answer 2

Answer:

halves

Explanation:

because if we increase the length of the wire resistance also increases. resistance is inversly proportional to the current if resistance increases current will decrease.if length is doubled ,current will it's halves.
