For a given time step h, starting from the given initial state of the dynamic elements, the circuit response is calculated at t 0 + h using a first- order numerical integration method. In this way, the analysis of a linear dynamic circuit can be done by solving a linear resistive circuit at each time step.
An electrical circuit containing at least one dynamic circuit element (inductor or capacitor) is an example of a dynamic system. The behavior of inductors and capacitors is described using differential equations in terms of voltages and currents. The resulting set of differential equations can be rewritten as state equations in normal form.

The aim of this study was to demonstrate that the dynamic equivalent circuit can be used to model the behaviour of supercapacitors if one allows for an interpretation in terms of a distribution of relaxation times.
The behavior of dynamic circuits, consisting of independent sources, inductors, capacitors, and resistors, is described by a system of differential equations. A first-order linear circuit contains only one dynamic element (an inductor or a capacitor), other linear circuit elements (resistors, linear controlled sources), and independent sources.
We use the denition of capacitance, C= Q=V and consider the circuit to be a single capacitor in a black box with two wires sticking out left and right. The voltage applied is that supplied by the power source, namely V. The charge that goes into the box through the wire on the left is the sum of the charges that go onto capacitors 1 and 2.

If a circuit contains nothing but a voltage source in parallel with a group of capacitors, the voltage will be the same across all of the capacitors, just as it is in a resistive parallel circuit. If the circuit instead consists of multiple capacitors that are in series with a voltage source, as shown in Figure 8.2.11, the voltage will divide between them in inverse proportion. In other words ...
