LIST OF EXERCISES/PRACTICALS ‘The practical/exercises should be properly designed and implemented with an attempt to develop different types of skills (outcomes in psychomotor and affective domain) so that students are able to acquire the competencies/programme outcomes. Following isthe list of practical exercises for guidance. Note: Here only outcomes in psychomotor domain are listed as practical/exercises. However, if these practica/exercises are completed appropriately, they would also lead to development of certain outcomes in affective domain which would in turn lead to development of Course Outcomes related to affective domain. Thus over all development of Programme Outcomes (as given in a common list at the beginning of curriculum document for this programme) would be assured. Faculty should refer to that common list and should ensure that students also acquire outcomes in affective domain which are required for overall achievement of Programme Outcomes/Course Outcomes. - Approx Ne | cos Practical/Exercises Hrs. | required 1 | 1,2. | Draw electrical and electronic symbols using CAD and take print out. 02 © 2 |_| Draw D.C. and A.C machine pars using CAD and ake printout o4 Draw different types of rectifier circuit using CAD and take print out 3 | 1, of a) Single phase half wave, (b) Single phase full wave, a (©)Bridge rectifier. 4 | 2 | Draw R-C couple amplifier circuit using CAD and take print out 2 Draw the following oscillator circuit using CAD and take print of (a) Hartley oscillator, (b) Colpitt oscillator, (c) Phase- 5 2 | shin Oscillator, (d) Wien Bridge Oscillator, (¢) Crystal o4 Oscillator, ‘Simulate three resistances in series circuit and find out voltage and 6 | 3 | current in each resistance o ‘Simulate the following circuits and find out voltage and current in 7 | 3. | each resistance.

LIST OF EXERCISES/PRACTICALS ‘The practical/exercises should be properly designed and implemented with an attempt to develop different types of practical skills (Course Outcomes in psychomotor and affective domain) so that students are able to acquire the competencies (Programme Outcomes). Following is the list of practical exercises for guidance. Note: Here only Course Outcomes in psychomotor domain are listed as practical/exercises. However, if these practical/exercises are completed appropriately, they would also lead to development of Programme Outcomes/Course Outcomes in affective domain as given in a common list at the beginning of curriculum document for this programme. Faculty should refer to that common list and should ensure that students also acquire those Programme Outcomes/Course Outcomes related to affective domain.Sr. . . ‘Approx. xe | cos Practical/Exercise His, Required Obtain magnetizing characteristics (open circuit) of seif excited DC| 1 12 | shunt generator. 4 ‘Load self excited DC shunt generator to obtain its external & internal] 2 12 | characteristics. 4 Load self excited DC series generator to obtain its external & internal] 3 | 12 | characteristics 4 Load self excited DC compound generator to obtain its external &| ‘ 1.2 | intemal characteristics. 4 Perform speed control on DC shunt motor.
