MCQ Practice Question

In an overdamped second-order circuit, the characteristic roots are typically?

ATwo distinct negative real roots for a stable passive circuit
BA repeated imaginary pair
CA complex-conjugate pair with zero real part
DOne root only at the origin

Correct Answer: A. Two distinct negative real roots for a stable passive circuit

Explanation: Overdamping gives two distinct real roots; in a stable passive circuit both are negative and produce nonoscillatory decaying exponentials.
