Prepare the UGC CSIR net question papers those are enough. The question paper will be of 50 questions in size each 3 marks and with a negative of -1 for each wrong answer
Ecil,
2986a solar energy installation utilizes a three phase bridge converter to feed energy into power system through a transformer of 400v/400v.the energy is collected in a bank of 400v battery and is connected to converter through a large filter choke of resistance 10ohms.1.the maximum current through the battrey will be.2.the kva rating of the input transformer is.
