Q. When the quantum step size δv and the step size of f (t) are the same as in , the quantizer is said to have a gain of unity. If, on the other hand, the quantizer has a gain of K

Circuit with inductive load  Electromagnetic induction When a conductor is moved across a magnetic field so as to cut by the lines of force (or flux, an electromotive force

#### Calculate rotor copper losses, A 20 h.p. , 3 phase, 400 volt, 60 hertz, 4 p...

A 20 h.p. , 3 phase, 400 volt, 60 hertz, 4 pole induction motor delivers full load at 5% slip. The mechanical rotational losses are 400W. Calculate (a) The electromagnetic torqu

#### The a.c/d.c. generator - electromagnetic torque, Note, the armature curren...

Note, the armature current is produced in pulses as the armature rotates under the poles, so the torque also pulsates. This can give rise to extra wear on bearings and the engin
