A wire is bent in form shown below. Length of wire
is 8 m and resistance is 5 2/m. The resistance
between point A and B is
B​

Answer 1

Given:

The resistance of wire R= 5 ohm

The length of wire l= 8 m

To find:

The resistance between A and B

Solution:

The R1 resistance of A and R2 resistance of B

R1=R2=R/2=2.5

The formula of equivalent resistance.

R'=R1×R2/R1+R2

R'=2.5×2.5/2.5+2.5

R'=1.25

So the resistance between the point A and B is 1.25 ohm.
