Answer 1

Answer:

200/19 percent

Explanation:

Resistance=Resistivity*length/area

Let length of the wire be,100.

It's new length=100+5/100*100=105

Let Resistivity be, a and area be, b.

Old resistance=100a/b

new resistance=105a/(95b/100)=2100a/19b

Change=2100a/19b-100a/b=200a/19b

Change%=(200a/19b)/(100a/b)*100=200/19%
