Dear Sirs
I need to draw some simple eletrical circuits. I try metapost (
mpcirc.mp) and cicruitikz, but i found error messages in both.
Is there a way to draw eletrical circuits in ConTeXt?
Thanks in advance for your support.

With this code:
\startMPinclusions
input mpcirc;
\stopMPinclusions
\starttext
%\forceMPTEXgraphictrue %%% command don't work
\startMPcode
u:=10bp; % unit of length
prepare(L,C,Vac); % mention your elements
z0=(10u,10u); % lower right node
ht:=6u; % height of circuit
z1=z0+(0,ht); % upper right node
C=.5[z0,z1]; % location of capacitor
L.t=T.r; % use default orientation
C.t=Vac.t=T.u; % components rotated 90 degrees
% set the distance between Voltage and Capacitor
equally_spaced(5u,0) Vac, C;
L=z1-0.5(C-Vac); % location of spool
edraw; % draw components of the circuit
% draw wires connecting components
% the first ones rotated 90 degrees
wire.v(Vac.a,z0);
wire.v(Vac.b,L.a);
wire.v(L.b,z1);
wire(C.a,z0);
wire(C.b,z1);
\stopMPcode
\stoptext
I found this error message:
metapost > error:

############ With Circuitikz #######
If i try use Circuitikz with this test code:
\usemodule[circuitikz]
\starttext
A simple example to test the installation.
\startcircuitikz[scale=1.2]
\draw
(0,2) to[I=1\milli\ampere] (2,2)
to[R, l_=2\kilo\ohm, *-*] (0,0)
to[R, l_=2\kilo\ohm] (2,0)

to[cspst, l=$t_0$] (4,2) -- (4,1.5)
to [generic, i=$i_1$, v=$v_1$] (4,-.5) -- (4,-1.5)
(0,2) -- (0,-1.5) to[V, v_=4\volt] (2,-1.5)
to [R, l=1\kilo\ohm] (4,-1.5);
\stopcircuitikz
