Difference between Alternator and Generator. By Yuvi - Study Point

Hey everyone, today we are going to see the simple difference between Alternator and Generator.
So, without wasting any time lets get started.

  • Alternator 
  1. An alternator is a machine that converts mechanical energy from a prime mover into the A.C electrical power at a specific frequency and voltage.
  2. Alternator induces an alternating current.
  3. The input supply in the alternator is taken from the stator. 
  4. The alternator has a variable output e.m.f.
  5. The alternator is smaller in size as compared to the generator and that's why it requires less space as compared to the generator.
  6. The output of the alternator is higher than the generator.
  7. The alternator has a wide range of rotation per minute (RPM).
  8. The armature of an alternator is stationary which means in an alternator, electricity is produced when the magnetic field spins inside the stator (winding of wire).   
  9. The alternator has a rotating magnetic field.
  10. A dead battery is can't be charged by an alternator and if we try to charge it then there is a possibility that it will burn out.
  • Generator
  1. The generator can convert mechanical energy from the prime mover into A.C or D.C electrical power.
  2. Alternating current can be produced by an alternator and this alternating current is converted into direct current with the help of commutator.
  3. The input is taken from the rotor in the generator.
  4. The generator's output voltage is constant.
  5. The generator's size is greater than the alternator and hence it requires large space as compared to the alternator.
  6. The generator's output is low as compared to the alternator.
  7. The generator has a narrow range of RPM (rotation per minute).
  8. In the generator, the armature is rotating which means the winding of the wire in a generator spins inside a fixed magnetic field to generate electricity. 
  9. The generator has a stationary magnetic field.
  10. The generator can be used for charging a dead battery.

NBFM & WBFM (Narrow band frequency modulation & Wide band frequency modulation) simple explanation. By Yuvi - Study Point

Hey everyone, today we are going to learn about NBFM & WBFM (Narrowband frequency modulation & Wideband frequency modulation) in simple or easy way. So, without wasting any time lets get started. The information about NBFM & WBFM When the spectrum's efficiency is important or it is required then we use NBFM (Narrowband frequency modulation) is used.  But when better signal quality is required or when it is important then we use WBFM (Wideband frequency modulation). The term NBFM is used for those applications where the modulation index is less than or equal to 1. And the term WBFM is used for those applications where the modulation index is greater than or equal to 1. Now, let's see more difference between Narrow band frequency modulation(NBFM) and Wideband frequency modulation(WBFM). The term narrow-band and wide-band refer to the actual radio channel bandwidth. The purpose or advantage of using NBFM (Narrowband frequency modulation) The purpo...

RVDT (Rotary variable differential transformer or transducer) simple explanation. By Yuvi - Study Point

Hey everyone, today we are going to simply learn about RVDT (Rotary variable differential transformer). So, without wasting any time lets get started. RVDT is a passive transducer which means it requires an external power source. Its designing is same as like LVDT (Linear variable differential transformer o transducer) but the main dissimilarity is that RVDT has a cam-type core or we can say rotary ferromagnetic core which means the shape of the core is different because LVDT consists or employs flexible iron core for displacement.   And by the help of shaft, this core will turn or rotate among the two windings of the transformer. The shape of an RVDT is cam-shaped. Three conditions which occur is RVDT is ~ *when the core or shaft is placed at the null position then the induced e.m.f in secondary windings are similar as well as revers in phase. E0 = E1- E2 = 0 *When the core rotates in a clockwise direction, in this the more section of the core will enter ...

Corona effect in transmission lines.| Explanation by Yuvi - Study Point

You all have heard about the Corona effect in transmission lines, now understand it in a simple way. This effect is a phenomenon which is associated with all transmission lines. At certain conditions, the electric field closer or near the energized conductors or components produces a tiny electric discharge or we can say corona which causes the surrounding air to ionize. And due to this ionization of surrounding air molecules of conductors, a luminous glow with hissing noise is produced which is known as Corona effect. Between the transmission lines, air act as a dielectric medium or we can say that air act as an insulator between current-carrying conductors. Between the conductors, voltage induces and if this voltage is of alternating nature then charging current will flow between the conductors. And the voltage of this transmission line and electric field intensity increases because of this charging conductor. There is a predetermined value of the electric field inten...
