What have we modelled here?

(a) A capacitor which is blocking DC

(b) An inductor which is blocking AC

(c) A resistor whose resistance changes with temperature

(d) A capacitor which is being charged

This question was addressed to me during an interview for a job.

The doubt is from Modeling in portion SIMULINK and GUIs of MATLAB

Right answer is (a) A capacitor which is blocking DC

The explanation: The output of the derivative block will be 0. Hence this system shows a model of the event described in capacitor which is blocking DC. Note that to model option inductor which is blocking AC, we need an integrator which takes a high frequency sinusoid.
