Q.1 Explain (i) Hysteresis loss (ii) Eddy Current Loss
Q.2 Two coils A and B are mutually coupled so that 55% of the flux of Coil A links Coil B. It is found that current of 2A produces a flux of 0.04 mWb in coil A while the same current in B creates in it flux of 0.05 mWb. If Number of turns are 1000 and 1300 respectively Find LA and
LB of coil A & B respectively(b) Mutual inductance (C) coefficient of coupling.
Q.3 Give comparision of electric circuit and magnetic circuit.
Q.4 eee A 10 ohm resistor is connected to 200 Volt sinusoidal 50 Hz supply. Find the peak, rms and average values of the current and also find power dissipated in resistor.
