Direct manipulation is the ability to manipulate the digital world inside a screen. A Touch screen is an electronic visual display capable of detecting...
by Tarun Agarwal 11 years ago AC Power Supplies at Home Ever wondered how does electricity comes to your house or suppose if the power is off, how you are still getting electricity at home. Actually there can be many ways to get AC power supply without actually having to stay without electricity. 4...
by Tarun Agarwal 11 years ago Industrial Star Delta Starter for a 3-Phase Induction Motor A 3 Phase Induction motor consists of a stator which contains 3 phase winding connected to the 3 phase AC supply. The arrangement of the winding is so as to produce a rotating magnetic field. The rotor of the Induction motor contains cylindrical...
by Tarun Agarwal 11 years ago Soft Starter – Principle and Working A soft starter is any device that controls the acceleration of an electric motor using controlling the applied voltage. Now let us have a brief recall of the need for having a starter for any motor. An Induction motor can self start owing...
