A single-phase transformer has 2400 turns on the primary and 600 turns on the secondary.
Its no-load current is 4A at a power factor of 0.25 lagging.
Suppose the volt drop in the windings is negligible, measure the primary current and power factor when the secondary current is 80A at a power factor of 0.8 lagging.
Question As-per to the law of reflection the angle of reflection is equal to the angle of incidence. An angle is at all times an angular separation between two planes a direct

what is Friction When we think about friction, there is one more place for energy to go - heat. When you push a book across a table, does the energy of the book change? Not if in
Explain Scalars and Vectors This is one of the harder ideas to get used to when you start learning physics. The trick is to see that there is one basic difference between a sca
Hello, I''d like to ask, why do objects, that fall from higher heights hit stronger that those, falling from smaller heights, if force equals mass times acceleration, and yet accel
