  • If frequency remain same and we increase the size of antenna then what will be the beam width.

  • decrease

  • in an induction motor if airgap is increases then power factor of the motor gets decreases because the motor draws more magnetizing current which lags the voltage by a more angle. if the angle b/w voltage and current is more then the power factor will be less.

  • absolutely it is decrease. As the inductive reactance increases, impedance increases hence powerfactor reduces.

  • IF AIR GAP IS MORE THAN PF WILL REDUCE BECAUSE LEAKAGE FLUX IS MORE FROM STATOR TO ROTOR.

  • decrease

  • power factor will decrease and will be lagging . because increase in airgap causes stator winding to draw more magnetization current which causes total resultant current to Lagg more behind applied voltage and finally power factor will decreas

  • Power factor decrease

  • if air gap increases the magnetising current Im draws from the supply increases .the Im is inversely proportional to the power factor,from this Im increases p.f decreases
