In
your circuit toolbox you have only some 10 resistors and switches, which can be open or closed. Construct a circuit, filling
in all four boxes, such that the overall equivalent resistance between A and B is 20 22.
A+
B

Expert Solution

Step 1: Find out equivalent resistance using all four boxes and without using any switch:

$The space equivalent space resistance space of space each space segment space is space left parenthesis 10 plus 10 right parenthesis space straight capital omega equals 20 space straight capital omega Here space equivalent space resistance space between space AB space is space colon straight R subscript AB equals fraction numerator 20 cross times 20 over denominator 20 plus 20 end fraction equals 10 space straight capital omega$

So we must use key to get our required value of equivalent resistance.
