Detailed Solution for Technical Test SSC JE: Electrical Engineering (EE)- 8 - Question 4

The units of deflection sensitivity of the CRO is – meter per volt.

CRO stands for Cathode Ray Oscilloscope. It is an electronic device with the CRT as its main component and other associated circuits. The CRO has horizontal and vertical plates in between the electron gun and the screen in order to deflect the beam according to the input signal.

The deflection sensitivity of a CRO is defined as the vertical deflection of the beam on the screen per unit deflecting voltage. 

It is also defined as the deflection produced per volt of deflecting voltage. Therefore, the units of deflection sensitivity of the CRO is – meter per volt (m⋅V−1).

Detailed Solution for Technical Test SSC JE: Electrical Engineering (EE)- 8 - Question 6

Ns = (120 × f)/P

= (120 × 50)/6

= 1000 rpm
Rotor speed = Ns – SNs = 950 r.p.m.
Stator magnetic field speed, Ns = 1000 r.p.m.
Rotor magnetic field speed, Ns = 1000 r.p.m.
Relative speed between stator and rotor magnetic fields is zero
Rotor speed with respect to stator magnetic field = 950 – 1000 = – 50 r.p.m.
