Q:

Use an electrical equivalent model $($also known as lumped element model$)$ to demonstrate the capability to recognise the main characteristics of a source generating an analogue signal, and model them with electrical components, such as a capacitor, an inductor, etc. $($An example could be the stiffness of a membrane which is electrically modelled as a capacitance, if an $$impedance model$$ is used$).$ Expand on the assumptions used to produce the model, on its accuracy $($e$.$g$.$ in the frequency domain$),$ and its validity
