How can three resistors of resistances $2\ Ω$ , $3\ Ω$ , and $6\ Ω$ be connected to give a total resistance of (a) $4\ Ω$ , (b) $1\ Ω$ ?

a. $4\ Ω$

The equivalent resistance of the resistors is

$\begin{array}{l} \frac{1}{R_{P}} = \frac{1}{R_{i}} + \frac{1}{R_{i}} \\ = \frac{i}{i} \\ R = i Ω \end{array}$

$R_{eq}$

$=$

b. $1\ Ω$

The equivalent resistance is

$\begin{array}{l} \frac{1}{R_{P}} = \frac{1}{R_{i}} + \frac{1}{R_{i}} + \frac{1}{R_{i}} \\ R = i Ω \end{array}$
