2.9
In the following circuit, it is observed that for $i = 0$ and $v = 1$ V, $i_L = rac{1}{2}$ A,
while for $i = 1$ A and $v = 0$, $i_L = rac{1}{2}$ A.
$R$

$i_L$
$R$

$2R$
$v$
$b$
$R_L$
(a) Determine $i_L$ when $i = 4$ A and $v = 2$ V. (You do not need the values
of $R$ and $R_L$ to answer this part; just make use of the results of
Problem 2.8.)
(b) Determine the values of resistances $R$ and $R_L$.
(c) Is it possible to change the value of $R_L$ in order to increase the power
absorbed in $R_L$ when $i = 4$ A and $v = 2$ V? Explain.
