Bond graph example: An electrical circuit
=========================================
Here we show an electrical circuit with static storage (capacitor C), dynamic storage (inductor L) and dissipation (resistor R).
:math:`v_in^e` and :math:`v_out^e` are the input and output fluxes (electrical currents), respectively.
:math:`v_C^e`, :math:`v_R^e` and :math:`v_L^e` are the currents flowing through capacitor C, resistor R and inductor L, respectively, and :math:`u_C^e`, :math:`u_R^e` and :math:`u_L^e` are the electrical potentials across them.
Superscript ‘e’ indicates that the variables are electrical quantities; subcripts indicate the location in the circuit for each quantity.

:alt: Schematic and bond graph of the model
A simple electrical circuit (a) with its representation by a bond graph (b). 0:nodes for an electrical network are physical locations where the flows (electrical currents) are balanced, while 1:nodes represent circuits around which the potentials sum to zero. :math:`v_in^e` and :math:`v_out^e` are boundary conditions.
The **Views Available** menu to the right provides various options to explore this model here in the Physiome Model Repository.
Of particular interest is the *Launch with OpenCOR* menu item, which will load the simulation experiment shown below directly into the `OpenCOR`_ desktop application.
