Why is hysteresis undesirable in a measuring instrument?

Why are eddy currents undesirable in transformers?
Answer : Eddy currents are undesirable in transformers because they cause **energy loss** and **heat generation**, which can reduce the efficiency of the transformer. Here's how: 1. **Energy ... currents. By minimizing eddy currents, transformers can operate more efficiently and with less heat generation....

Explain the working principle of a Moving Iron (MI) instrument. How does it differ from a Moving Coil (MC) instrument in terms of construction, operation, and applications?

Explain the working principle of a Moving Iron (MI) instrument. How does it differ from a Moving Coil (MC) instrument in terms of construction, operation, and applications?
Answer : **Working Principle of Moving Iron (MI) Instrument:** A Moving Iron (MI) instrument works on the principle of electromagnetic attraction. When current flows through a coil, it creates a magnetic field. This ... galvanometers and ammeters. Let me know if you'd like me to add or tweak anything!...

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 if lamp efficiency is 20 lumens/watt. Assume and write suitable values of constants required for this calculation.
