A series motor is now constructed from this machine by leaving the shunt field out entirely. Derive the torque-speed characteristic of the resulting motor.
A narrow beam of electrons is pointed, in vacuum, directly towards a very small spherical target that carries a negative charge of Q = -2x10-11 C. The initial kinetic energy of an individual electron in the beam is ε0 = 100 eV (1 eV = 1.6x10-19 J)
Estimate the straight voltage gain for the amplifier of Example 3.7
1) For a semiconductor E vs kx near the band edge Ec is given by E=Ec +(h2/16m0)*kx2 Determine the effective mass of electrons in the conduction band. Here m0 is the mass of a free electron. 2) E vs. kx for electrons near the valence band edge Ev can..
What is the rate at which the electric field between the plates is changing?
For the network of given figure (a), determine the value of R2 for maximum power to R4.- Is there a general statement that can be made about situations such as those presented here and in given Problem?
A long wire carrying a 5.0 A current perpendicular to the xy-plane intersects the x-axis at x = -2.0 cm. A second, parallel wire carrying a 3.0 A current intersects the x-axis at x = +2.0 cm.
a) Consider an n-p-n transistor whose base emitted drop is0.76 at a collector current of 10mA, What current will it conductat Vbe=0.70V. What is the base emitted voltage for ic=10microampere. b)A CE amplifier uses a BJT with B=100, Va=50V, biased a..
To reduce the starting current, a three-phase squirrel-cage induction motor is started by reducing the line voltage to Vs/2. By what factor are the starting torque and the starting current reduced?
Discuss differential protection, modified differential protection and percentage differential protection of alternators. Draw the suitable connection diagrams for clear understanding.
At what temperature do hydrogen molecules, H2, have the same rms speed as nitrogen molecules, N2, at 455C. At what temperature do hydrogen molecules have the same average kinetic energy.
Describe the two spin echo methods (1.Hahn, 2. CPMG-Purcell et. al). Describe the role of p/2 and p pulses in each case and make a comparison and contrast. Give diagrams
An amplifier provides 10.5 V output under unloaded condition. When a load of 10-ohm is connected at its output, the voltage drops down to 0.5 V. Find out the output resistance of the buffer that is to be put between the amplifier
