Question

When deriving the transfer function of a linear element

(a) Both initial conditions and loading are taken into account

(b) Initial conditions are taken into account but the element is assumed to be not loaded

(c) Initial conditions are assumed to be zero but loading is taken into account

(d) Initial conditions are assumed to be zero and the element is assumed to be not loaded

The question was posed to me in an online quiz.

The doubt is from Transfer Functions topic in division Mathematical Models of Physical Systems of Control Systems

Answer 1

The correct answer is (c) Initial conditions are assumed to be zero but loading is taken into account

The best I can explain: When deriving the transfer function of a linear element only initial conditions are assumed to be zero, loading cannot be assumed to be zero.
