This is the sheme i've made :

enter image description here

And the code is:

\begin{circuitikz}[european]
\draw (0,0) to[sV,l_=$u_G$] (0,2.7) to[generic,l=$R_G$,i_=$i_{ul}$](2.5,2.7) to[generic,l_=$h_{ie1}$,i=$i_{b1}$] (5.2,2.7) to[short] (7.9,2.7);
\draw(2,2.7) 
(1.45,2.2) to [short] (1.45,2.2) node[anchor=west] {+}
(1.55,0.45) to [short] (1.55,0.45) node[anchor=west] {-};
\node at (1.7,1.35) {$u_{ul}$};
\draw(2.5,2.7)node[above=0.0cm]{$B_1$}  to [generic,l={$R_{B1}$},*-] (2.5,0);
\draw(5.2,0)node[below]{$C_1$} to[american current source,l=$h_{fe} i_{b1}$, *-*] (5.2,2.7)node[above=0.0cm]{$E_1$};
\draw(6.55,2.7) to [generic,l=$R_{E1}$,i=$i_{e1}$] (6.55,0);
\draw(7.9,2.7) node[above=0.0cm]{$B_2$} to[generic,l=$R_{B2}$,i=$i_{B2}$](7.9,0) ;
\draw(7.9,2.7) to [generic,l_=$h_{ie2}$, *-*,i=$i_{b2}$] (10.6,2.7)node[above=0.0cm]{$E_2$} ;
\draw(10.6,2.7) to [generic,l=$R_{E2}$,i=$i_{e2}$,-*](10.6,0)node[below]{$C_2$};
\draw(12.85,2.7) to[generic,l_=$R_{C2}$](12.85,0);
\draw(12.85,2.7) to(14.2,2.7)to [generic,l_=$R_{p}$,i=$i_{iz}$](14.2,0);
\draw(12.85,2.7) to[american current source,l=$h_{fe} i_{b2}$](10.6,2.7);
\draw(15,2.7) 
(14.8,2.2) to [short] (14.8,2.2) node[anchor=west] {+}
(14.9,0.45) to [short] (14.9,0.45) node[anchor=west] {-};
\node at (15.05,1.35) {$u_{iz}$};
\draw (0,0)--(14.2,0);
\draw[red,dashed,thick,rounded corners,-latex] (2.9,1.55)--([shift={(0.9,-0.5)}]2,2.7)-- ([shift={(-0.5,-0.5)}]10.6,2.7)--
([shift={(-0.5,0.5)}]10.6,0)-- ([shift={(0.5,0.5)}]2.4,0);
\end{circuitikz}

How could I move the i_{iz} part so it'll be like here

I won't do your homework for you, but I can help to explain the positioning of currents in circuitikz, which should help you complete assignments like this in the future.

A complete location spec for current labels is comprised of

  • one of ^/_ to specify the position of the label above/below the component (where above and below is from the point of view of a component drawn from left-to-right), and
  • one of >/< to specify the direction of the current towards/opposing the drawing direction of the component.

The order of the symbols determines whether the current is placed before or after the component: if the direction specifier comes first, the current is drawn before the component in the path, while if the direction specifier is last, the current is drawn after the component in the path.

The default location spec for currents is ^>. In the absence of either specifier, its default will be used.

This short example should give an illustration of all the possibilities:

\documentclass{standalone}
\usepackage{circuitikz}
\newcommand{\labeltest}[2]{\draw (#1) to[generic,i#2=$i_1$] +(0,2);}
\begin{document}
\begin{circuitikz}
  \labeltest{0,0}{} % default position (no specification)
  \labeltest{1,0}{^>} % current in drawing direction (up), current after component, label above (if drawn left-to-right)
  \labeltest{2,0}{_>} % current in drawing direction, current after component, label below
  \labeltest{3,0}{^<} % current opposes drawing direction, current after component, label above
  \labeltest{4,0}{_<} % current opposes drawing direction, current after component, label below
  \labeltest{5,0}{>^} % current in drawing direction, current before component, label above
  \labeltest{6,0}{>_} % current in drawing direction, current before component, label below
  \labeltest{7,0}{<^} % current opposes drawing direction, current before component, label above
  \labeltest{8,0}{<_} % current opposes drawing direction, current before component, label below
\end{circuitikz}
\end{document}
