Here is my MWE taken from Flow of current in a circuit, except for the additional current direction at battery as well as one additional arrow mark using \draw [<-, >=latex]
\documentclass{article}
\usepackage[american,siunitx]{circuitikz}
\begin{document}
\begin{circuitikz}[]
\draw [<-, >=latex] (-1.3,0.8)--(-1.3,1.3);
\draw (0,0) to[battery, l=12<\volt>, i>^=$I_{B}$, >=latex] (0,2) -- (0,3.5)
to[R,l=4<\ohm>,i_=$I_1$] (4,3.5) -- (4,2)
(0,0) -- (4,0) to[battery, l=24<\volt>,i>] (4,2)
(0,2) to[R, l=2<\ohm>, *-*,i_=$I_2$] (2,2)
to[R, l=3<\ohm>, -*,i<_=$I_3$] (4,2)
(2,0) to[R, l=2.5<\ohm>, *-,i<_=$I_4$] (2,2);
% \draw[ultra thin,color=gray!30, step=1cm, ] (0,0) grid (6,4);
\end{circuitikz}
\end{document}
How to use >=latex locally within circuitikz such that, arrow tips of current flow directions through all elements look like the arrow mark shown left of the battery?

circuitikzarrows are not arrows in the TikZ sense, they are shapes. If you want to use different types of arrows, look at the "advanced voltage and currents". – Rmano Sep 10 '22 at 22:34
