Yes, you can form arbitrary orders of differential equations with electric circuits. These circuits are called filters, and we also talk about the order of the filter, which is equivalent to the order of the differential equation

When you go to integrate differential equations, each independent energy-storage element will require one initial condition. The number of independent energy-storage elements is the
6 FAQs about [Energy storage element differential]
What is a modulated energy storage element?
The reason for this restriction is that a modulated energy-storage element would mean that the total energy in a system would be a function of the modulating input or set of inputs. Consequently, the total energy in the system would not be equal to the net power flow in across the system boundaries..
Why do we need to know about dependent energy storage elements?
This is a typical consequence of dependent energy storage elements and, as one might expect, in more complex systems the algebraic manipulations can become formidable, even prohibitively so. It would be useful to know about dependent energy-storage elements before attempting to derive equations. How may we do so?
Which energy storage element can be described using an integration operator?
Every energy-storage element which can be described using an integration operator should be. It will require one initial condition to determine its constant of integration, and therefore will give rise to one state variable; energy storage elements which have integral causality are independent.
What is inter-dependence of energy storage elements?
That is the true meaning of inter-dependence of energy storage elements: in the model they are not distinct energy storage elements, despite appearances to the contrary. These two modelling approximations — rigid-body models and time-derivative operations — are intimately related.
Do energy storage elements have integral causality?
The entire collection of mass points is a single independent energy storage element; a single number (the common momentum or common speed) is sufficient to determine the stored energy. A point to be taken from this discussion is that, if possible, energy-storage elements should be independent and have integral causality. But why?
Which energy storage element does not give rise to a state variable?
Conversely, any energy storage element which must be described using a derivative operation will not require an independent initial condition and therefore will not give rise to a state variable; energy storage elements which have derivative causality are dependent.
