Calculate the steady state value for x(t)=7e^-9t.(a) 0(b) 8(c) 3(d) 1I had been asked this question by my school principal while I was bunking the class.My doubt is from Dynamic Braking of DC Shunt Motors topic in chapter Braking of DC Motors & Induction Motors of Electric Drives

Answer» CORRECT answer is (a) 0

The best explanation: The steady STATE value is OBTAINED at t=∞. The value of x(t) at t=∞ is 7e^-∞=4(0)=0. The TERM e^-9t is an exponentially decaying function.
