Sketch the waveform for the voltage induced across a 0.2-H coil if the current through the coil is as shown in given figure.
A certain transmission line is 10 meters long. Measurements indicate that the total inductance of the cable is 16 uH. Standing wave measurements indicate that the voltage reflection coefficient at the load is 0.5 + j0
What is the rotational speed of the motor at no-load conditions - Assuming no armature reaction, what is the speed of the motor at full load?
1. How is the LCD placed into the 4-bit data mode? 2. How is the cursor in an LCD positioned to a specific, user-selected location on the display? 3. Given the state of RS, E and R/W~, and the data (in hex) needed to send an 'H' to the LCD for disp..
Referring to Fig. 1.25d, a µF capacitor is charged to 12 V and then connected across a resistor of 100 Ω.
Find the maximum allowed developed torque and corresponding motor speed that will ensure that no more than 25% of the power is lost in conductive losses in the armature and field windings.
a. Find the closed-loop transfer function Y(s)/R(s) when G(s) =10/ (s2 + 4s-5) b. Determine Y(s) when the input R(s) is the Dirac delta function
a. if the input r(t)=5u(t), ie. R(s)=5/s, find the steady-state of C(t), b. Approximately how many seconds are required for the system to reach steady state note you two time constants to consider, and c. Do you expect the transient response to be o..
What Role Power factor play in AC circuits and power dissipation ? and What are the Disadvantages of Low Power Factor ??
A design problem: As we said earlier, the backbone of any design is ‘thorough analysis' of the problem or circuit at hand. We have analyzed above the voltage divider circuit. Utilizing the above analysis, determine R1 and R2 of a voltage divider c..
Three single-phase transformers, each rated 15 MVA, 13.2:66 kV, with a leakage reactance of 0.1 pu, are connected to form a three-phase Y-Δ bank, one side of which is connected to a 120-kV tranmission line and the other side, to three 12-ohm resis..
A coil with resistance 3Ω and inductance 100 mH is connectedin series with a capacitor of 50 pF, a resistor of 6Ω, and asignal generator that gives 110 V rms at all frequencies. Calculate ωo ,Q, and B at resonance of the resultant series RLC circu..
