5.a) List out the merits and demerits of Bridge type Full Wave rectifiers over centre tapped type Full Wave rectifiers. b) The secondary voltages of a centre tapped transformer are given as 60V-0V-60V the total resistance of secondary coil and forward diode resistance of each section of transformer secondary is 62 2. Compute the following for a load resistance of 1 KQ. i) Average load current ii) Percentage load regulation iii) Rectification efficiency iv) Ripple factor for 240 V/50Hz supply to primary of transformer. c) What is bleeder resistance in L-section filters? 6.a) Describe the significance of the terms, 'a' and 'B'. Establish a relation between them. b) A transistor is operated at a forward emitter current of 2 mA and with the collector open circuited. Assuming an = 0.98, IEO = 1.6 A and Ico = 2 A, determine i) The junction voltages Vc and VE ii) The collector to Emitter voltage VCE iii) The region of transistor operation (Saturation/Active/Cut-off). Assume any other values necessary. -
