A balanced, three-wire, star-connected, 3-phase load has a phase voltage of 240 V, a line current of 5 A and a lagging power factor of 0.966. Draw the complete phasor diagram
Design a four-bit shift register with a paralel load, usingD-flip-flops. There are two control inputs:shift and load. Whenshift t=1, the contents of the register are shifted by oneposition. New data are transferred into the register when load=1and..
a) Three delta-connected absorb 60 KW when connected to a 3 phase line. IF they are reconnected in wye, calculate the new power absorbed. b) Three 10uF capacitors are connected in wye across a 2300v, 60 Hz line.
A conducting filament containing a small 400 ohm resistor is formed into a square loop on the x-y plane as explained in the previous problem. Find I at t = 2*10^-4 sec if (a) \(B = 3cos(12000\pi t)a_z T\)
A system has the transfer function: g(s)=7(9) / s(s^2 +(7+9) s + 7(9) a). write this transfer function in polynomial form and pole-zero form.
gear box has ratio 8:1 to the .9-m diameter wheels. ARMATURE HAS SOURCE WHERE THE VOLTAGE CAN BE VARIED FROM 0 TO600--IGNORE ALL LOSSES. A) DETERMINED REQUIRED VALUE OF kφ to give a speedof 12.5 m/s at an armature V of 600Volts.
A 20 vrms, 60 hz ac source is in series with an ideal diode and a 100 ohm resistance. Determine the peak current and peak inverse voltage (PIV) for the diode
The sun is at an altitude of 30 degrees to the horizontal. What is the corresponding air mass What is the physical significance of air mass Mars has a very thin atmosphere containing primarily CO_2 and dust particles.
A three 120 - V power line is Y-connected. The three phase outputs are marked as a,b,c. The neutral is marked as n. The phase sequence is abc. It is connected to a balanced Y- connected load, with the impedance is 12 + j 9 omega.
what is context based arithmetic coding?and it is calculated .
A column has a rectangular cross section with 14×14 inch dimensions. The steel is made up of 4#10 bars and #4 ties.
