(a) For the Zener diode series voltage regulator shown in the Figure. calculate VL, IZ, VR and PZ for RL= 1.2 KΩ and repeat it for RL= 3 KΩ ?
Consider Zener breakdown voltage = 10 V and PZM = 30 mW
(b) Calculate Q point ( IC, VCE) for the network shown? Assume β = 75
Using Bode plot calculate (a) Phase margin (b) Gain margin (c) Stability of closed loop system. The open transfer function of the system is t=30/(s+2)/(s+3)Using Bode plot calcula
Q. Planning and Research in power system? Energy research worldwide is assuming top priority, in particular because of economic, en - vironmental, and resource constraints. DOE
Q. Counting to moduli other than 2 n is a frequent requirement, the most common being to count through the binary-coded decimal (BCD) 8421 sequence. All that is required is a four
Athree-phase,wye-connected, 220-V, 10-hp, 60- Hz, six-pole inductionmotor (using Figure 13.2.6 for notation) has the following parameters in ohms per phase referred to the stator:
The aim of this question is to help you become familiar with phasor diagrams, and in particular to see how the diagram changes when one of the system parameters (in this case resis
What is the difference among 8085 and 8086 in microprocessor? Ans) 8086 has a special concept known as memory segmentation. It permits parallel processing, whereas 8085 does no
