draw simple vectors with latex

Question

Good evening everyone. I'm trying to learn how to deal with drawing packages in Latex but all I found on the web is too complicated for what I need to do. I guess if anyone of you can help me. basically I need to draw 6 vectors and giving names to them and to the angles. I can attach an image of what I need to realize. Can someone help me with a code which realize this, in order that I can then study it to better understand how things work?

Thanks very much in advance :)

Answer 1

as starting point (not reproduce your sketch, but on this basis you can see how to draw yours):

\documentclass[tikz,border=3mm]{standalone}
\usetikzlibrary{angles, arrows.meta, quotes}
\usepackage{siunitx}

    \begin{document}
 \begin{tikzpicture}[
            > = Straight Barb,
phasor/.style = {very thick,-{Stealth}},
angles/.style = {draw, <->, angle eccentricity=1,
                 right, angle radius=7mm}
                        ]
% coordinates
    \draw[->] (-0.5,0) -- (4,0) coordinate (x) node[below left] {$\mathit{Re}$};
    \draw[->] (0,-1.5) -- (0,2) node[below left] (y) {$\mathit{Im}$};
% phasors
    \draw[phasor] (0,0) -- (300:1.5) coordinate (i)  node[right] {I};% used polar coordinates
    \draw[phasor] (0,0) -- ( 30:2.5) coordinate (v)  node[right] {V};% used polar coordinates
% angles drawn by pic
\coordinate (X)   at (0,0);
\draw
    pic["$\theta=\phi-\SI{90}{\degree}$",angles] {angle=i--X--x}
    pic["$\phi$",angles] {angle=x--X--v}
    ;
\end{tikzpicture}
    \end{document}
