The circuit shown in figure is

The three terminal linear voltage regular is connected to a $$10\Omega $$ load resistor as shown in the figure. If $${V_{in}}$$ is $$10$$ $$V,$$ what is the power dissipated in the transistor

The common emitter forward current gain of the transistor shown is $${\beta _p} = 100.$$ The transistor is operating in

Consider the feedback system shown below which is subjected to a unit step input. The system is stable and has following parameters $${k_p} = 4,\,\,{k_i} = 10,\,\,\omega = 500\,\,$$ and $$\xi $$ $$=0.7.$$ The steady state value of $$z$$ is
