The resistance (r) in a wire increases when the length of the wire (l) increases. write the correct equation for this scenario, and solve for when the length is 1. length resistance 10 2 15 3 a. r = 20 over l; r = 20 b. r = .2l; r = 5 c. r = .2l; r = .2 d. r = 20 over l; r = 5

c. R = 0.2L ; R =0 .2

Step-by-step explanation:

Given: When length of wire is 10 units, then resistance of wire =2 ohm

When length of wire is 15 units, then resistance of wire =3 ohm

Since, the resistance (R) in a wire increases when the length of the wire (L) increases. Therefore, they are directly proportional.

Now, for Length L=1 unit, we have
