Consider the large inductor in Figure 3 with given number of turns N, core permeability μ, core cross section area A, and core diameter are given. Note that the core length l is equal to π times the core diameter. Answer the questions and pick an answer from the given choices. As a consequence, the practical inductor above can be represented by it inductance L in series with the resistance of the coil R (calculated above). Let this equivalent R-L circuit be connected to a 12 V source that has an internal resistance of 0.5 Ω as shown on the right hand side of Figure 3. Let switch SW2 be in the open position, while SW1 closed at t = 0.    Nearly how long will it take the inductor to fully charge (i.e., reach steady-state)? 1) 1.5 sec 2) 100 msec 3) 18.5 min 4) 37 sec

Compensation Techniques

The compensation techniques are the methods that are employed in the electrical control systems to enhance the performance of the system. The performance are generally affected by the factors like lag in the compensating devices, slow response of the system of the components like sensors used in the control system. The basic compensation technique involves lag compensation, lead compensation or the combination of the both.
