Question

In the given circuit calculate the following, Equivalent resistance between the points A and B. A) 5 B) 10 C) 20 D)15​

Answer 1

Answer:Rearranging the resistances the given circuit will form a circuit(Wheatstone's bridge) as shown in figure.

Let, r  

1

​

,r  

2

​

,r  

3

​

,and r  

4

​

 are the resistances in all branches, as bridge is balanced no current will flow through branch CD

Hence, equivalent resistance R is given by,

R

​

=
