while calculating the power absorbed by a resistor
connected to the output of a half wave rectifier circuit
should we use rms or average current? explain with reason.
how to calculate ups and battery rating
why transformer rating is always in KVA
why full load voltage is less than no load voltage?
can we connect both delta and star to the transformer secondary and for what reason?
Determine the minimum cable size for a 28A single phase final sub circuit originating from the distribution board supplied by three phase submain. The route length of the final sub circuit is 54 m. Assume 1% voltage drop in the consumer's mains. Submain specification: Cable: 50mm2 4 core V75 copper; Route length 42m; Maximum demand 135A per phase
The series field winding has low resistance while the shunt field winding has high resistance. Why?
motor work in hat principle generator work in what principle transformer work in what principle pls explain with details or answered to ramadoss.sepc@gmail.com
How will you Physically differentiate A.C and D.C motor?
what is the most permissible winding temp when we conducting a generator load test?(condition no load)
we all know that both the generator and motor are electromechanical conversion devices.....then why we rate motor in kw and generator in kva????
what is star&delta connections?
why only exciting current is shown not primary current in transformer???
