1.explain what is the instantaneous values of AC AND phase shift angle are. Explain what the effective and average values of AC are. How are they related with amplitude.
2.Draw a calculated conductivities triangle for the circuit with a parallel connection of RLC- elements and write down the corresponding relations for them .
3. Write down the complex effective values for given instantaneous values of voltage V=25sin(314t +pie/2)v and current I=0.5(314t+pie/3). Define the admittance of the circuit in complex fork ( ,exponential and Algeriac notation ), active and reactive conductivities . Draw the voltage and current vector diagram .
The springs effect is addressed below. As a relay some contacts are connected to, and move with, the armature. Other contacts are stationary and would make or break contacts as the armature moves.
a DC motor turns at a speed of 1460 rpm and produces an output torque of 3.0Nm. The DC voltage applied to the motor is 100V and a current of 5.1A flows through the motor. A. What is the efficiency of the motor
A DC source of 48V is connected to one end of the cable. The other end of the cable supplies a DC load. If the load current is 12.5 A, calculate the voltage drop due to the cable resistance and the laod voltage.
Using D-type flip-flops, design a synchronous Moore finite-state machine that monitors two inputs A and B, and asserts a scalar output if the number of 1s observed on the inputs is a multiple of 4.
A current source of 12 cos 2000t A, a 200-ohm resistor, and a 0.2-H inductor are in parallel. Assume steady-state conditions exist. At t = 1 ms, find the power being absorbed by the (a) resistor; (b) inductor; (c) sinusoidal source.
How does a squirrel cage induction machine differ from a wound rotor induction machine What are the advantages and disadvantages of each as a motor and as a generator
view an electrical substation that delivers power to a manufacturing plant, you notice large boxes with two terminals connected by wires to the substation network. What might be one function of these large boxes
In a balanced three-phase wye-wye system, the load impedance is 4 + j3 . The source has phase sequence abc and Van = 120
Make sure to mark significant points in your figure (amplitude, offset, time, etc.). How could a device be modified to work as an electro-optic phase modulator? If we apply signal V, what is the range of phase shifts induced by this modulator.
