GATE Electrical 2013 | Question: 28
The open-loop transfer function of a dc motor is given as $\dfrac{\omega (s)}{V_a(s)}=\dfrac{10}{1+10s}$.When connected in feedback as shown below, the approximate value of $K_a$ that will reduce the time constant of the closed loop system by one hundred times as compared to that of the open-loop system is $1$ $5$ $10$ $100$

GATE Electrical 2013 | Question: 26
A strain gauge forms one arm of the bridge shown in the figure below and has a nominal resistance without any load as $R_s = 300$ . Other bridge resistances are $R_1 = R_2 = R_3 = 300$ . The maximum permissible current through the strain gauge is $20\:mA$. During ... $V_0$ in $mV$ is $56.02$ $40.83$ $29.85$ $10.02$
