Question

The resistance is connected as shown in the figure below. Find the equivalent resistance between the points A and B.

205 $Ω$
10 $Ω$
3.5 $Ω$
5 $Ω$

The correct answer is: 5 $blank capital omega$

) 3 $blank capital omega$
R’=3+7=10 $capital omega$
R’ and 10 $capital omega$ are in parallel, so
$R to the power of ´ end exponent equals fraction numerator 10 cross times 10 over denominator 10 plus 10 end fraction equals 5 capital omega$
$R to the power of ´ end exponent a n d blank 5 capital omega blank$ are in series, so
R’=5+5=10 $capital omega$
Now, R’ and 10 $capital omega$ are in parallel, so
$R equals fraction numerator 10 cross times 10 over denominator 10 plus 10 end fraction equals 5 capital omega$
