A motor has to exert power starting from zero and rising uniformly to 150 HP in 8 mins after which it works at constant power of 100 HP for 5 mins. The motor remains on no load for next 5 mins. The cycle again starts and repeats indefinitely. Determine suitable size of motor.
Explain the experimental set-up for the Newton’s rings formation with suitable diagram. Write conditions for dark and bright rings.
A uniform illumination of 150 lux is to be obtained on the floor of a room measuring 15m x 15m by arranging electric lights suitably. Calculate the number of lamps and wattage of each ... lamp efficiency is 20 lumens/watt. Assume and write suitable values of constants required for this calculation.

PSC or CSIM motor. - **Mixers and grinders:** Universal motor or Capacitor-Start Capacitor-Run motor....
Why is a cycloconverter suitable for low frequency? Answer : A cycloconverter is suitable for low-frequency applications because it can directly convert a high-frequency AC supply to a lower-frequency output without using an intermediate DC stage. Here's ... way of stepping down the frequency while maintaining a good waveform for sensitive loads like motors....
