Advantages and disadvantages of traffic control signals on road
Advantages of traffic control signals on the road Traffic control signals provide for an orderly movement of traffic. They help in reducing the frequency of an accident of some special nature i.e. of right angles accidents. They
What is a failure of shunt generator to build up?
Causes of failure of voltage build-up or armature heating: No residual magnetism Without any residual magnetism, voltage build-up cannot start. Due to again in transportation, the machine may lose residual magnetism. This difficulty can be overcome by

Effect of variation of rotor resistance
Rotor resistance can be changed in case of wound rotor induction motor with help of external resistances connected and to brushes through slip rings provided a supply voltage and load remains constant. The starting torque hence speeds
