Does a circuit have memory?

Circuits that contain capacitors and/or inductors have memory. The voltages and currents at a particular time depend not only on other voltages at currents at that same instant of time but also on previous values of those currents and voltages.

Do two inductors contribute only one effective energy storing element?

So I would say that the two inductors together contribute only one effective energy storing element. Also, how sure are you about the correctness of the mechanical to electrical conversion?

Which circuit elements are represented by differential equations?

This chapter introduces two more circuit elements, the capacitor and the inductor. The constitutive equations for the devices involve either integration or differentiation. Consequently: Electric circuits that contain capacitors and/or inductors are represented by differential equations.

Which components add dynamic response to a circuit?

Here we will consider time responses of the circuit components. Components that add dynamic response to the circuit are capacitance and inductance. For example MOSFET does have internal capacitance in it’s structure, that we will consider here. Let’s consider the part of a circuit depicted below.

Are capacitances and inductances dynamic elements?

The first distinguishing feature of these elements is that they exhibit time-dependent characteristics, namely, i = C ( dv / dt) for capacitance and v = L ( di / dt) for inductance. For this reason, capacitances and inductances are said to be dynamic elements.
