Question

A long resistor between A and B has resistance of 3000
and is tapped at one third points.
CODE
10003250
What is equivalent resistance between A and
B?
22 omega
52 omega
32 omega
42 omega ​

Answer 1

Answer:

Consider the equivalent circuit of given circuit as shown in figure.

The equivalent resistance between X and Y from figure (c) is

RXY=160+4040×160 

RXY=2006400

RXY=32Ω

answer is 32 omega
