Extracted text: a) A steady current of 4 A is flowing through an inductor with 60 volts across it. Find (i) Inductance of the coil, if the current falls to zero in 180 ms, (ii) Energy stored in the inductor, (iii) Number of turns in the inductor for a flux of 45 mWb. b) A single phase 50 Hz, transformer with turns ratio of 75:1400 has cross sectional area of 190 cm² . When the primary winding is connected to 210 V supply. Determine (i) the maximum value of the flux, (ii) the maximum value of flux density in the core, (ii) Voltage induced in the secondary side of the transformer, (iii) load current, if the current in primary winding is 200 A.
