# Circuitikz: increase the distance of a resistor label

In such a simple circuit

\documentclass[12pt]{article}
\usepackage[siunitx]{circuitikz}
\usepackage{tikz}

\begin{document}

Resistance:

\begin{circuitikz}
\draw (0,0) to [R=$R$,*-*,v=$V_1 - V_2$] (2,0);
\end{circuitikz}

\end{document}


I would like to increase the distance between the label (so, the arrow and the $V_1 - V_2$ expression) and the resistor itself.

1) Hoping that it is possible, how can I do it?

2) Again, if possible, how can the arrow be bent a little bit more? If I change the scale to, say, 2.0, the arrow line appears almost straight.

• @MarcvanDongen Ok, I tried to include the code you suggested. – BowPark Mar 24 '15 at 16:06

You can use the voltage/bump b and voltage/european label distance parameters to do what you want:
\begin{circuitikz}
\draw (0,2) to [R=$R$,*-*,v=$V_1 - V_2$] (2,2);
\draw (0,0) to [R=$R$,*-*,v=$V_1 - V_2$] (2,0);
