Without using a truth table, find:(a) the minterm and maxterm expansions for F in algebraic and decimal forms (SOM,POM)(b) the minterm and maxterm expansions for F' in decimal form (SOM,POM).
F(A,B,C) = A + B'C' + BC
An overhead line conductor is supported at water crossing from two towers, the heights of the supports being 30 and 34.2 m respectively , above the water level , with a horizontal span of 325 m.
An object of mass m = 0:1 kg is dropped from a high tower. Suppose the magnitude of the force due to air resistance is 0:98v2. (The gravitational constant is g = 9:8 m s2 ). a) Write down the dierential equation satisfied by velocity.
An additional motor load of 100 kW is needed. Find the new kilovoltampere load and power factor of the plant load if the motor to be added is (a) an induction motor with a power factor of 90 percent lagging, and (b) an 80 percent leading power fac..
Design a combinational circuit that compares two 4-bit numbers to check if they are equal. The circuit output is equal to 1 if the two numbers are equal and 0 otherwise.
A terrestrial radio link transmits a CDMA signal from a base station using a spreading code with a chip rate of 1.0 Mchips per seconds. The message data rate of the signal is 10 kbps.
4.What is the fundamental benefit of PLC controls over manual controls 5.Describe the differences between the two methods of scanning during PLC logic solving. Which method holds the advantage over the other
A 100V dc series motor has an armature resistance of 0.2 ohm and field resistance of 0.25 ohm. The motor runs at a speed of 600 rev/min when the shaft torque is 27.14 Nm. Friction and windage losses at this speed are 300W.
The relative dielectric constant of the printed circuit board (PCB) is 4 and the microstrip lines have a characteristic impedance of 80W. The length of the microstrip lines are 30mm and 45mm, respectively.
A standard 12-V car battery has an ampere-hour rating of 30 Ah, whereas a heavy-duty battery has rating of 51 Ah. Calculate the ratio of available energy and the percentage increase in available current for starting.
A charged 100- picoFarad capacitor has initial voltage across it of 10 V. A 100 kohm resistor is suddenly connected across the capacitor (at t=0) to discharge it. What is the magnitude of the instantaneous current at 20 usec
Three parallel three-phase loads are supplied from a 207.85-V rms, 60-Hz three-phase supply. The loads are as follows: Load 1: A 15 hp motor operating at full load, 93.25 percent efficiency, 0.6 lagging power factor.
