Class 12 2023-24 Electricity and Electronics syllabus ISC: Here in this article ISC Class 12 students will be able to understand the Electricity and Electronics syllabus. In the list of electives offered by the Council of Indian School Certificate Examination (CISCE) to the ISC Class 11 and 12 students, the Electricity and Electronics subject is one of them. The subject code for Electricity and Electronics is 866. CISCE has mentioned certain points at the beginning of the syllabus. Let us have a look at those words of CISCE “ The syllabus is not intended to be used as a teaching syllabus or to suggest teaching order. It is expected that teachers will wish to develop the subject in their own way.
In the examination, questions will be aimed more at testing the candidates' understanding of fundamental principles, and the application of these principles to problem situations, than to their ability to remember a large number of facts. Some questions will include simple calculations. An experimental approach to the subject is envisaged and it is assumed that candidates will spend adequate time on individual experimental work. Questions may be set requiring descriptions of experimental procedures. Candidates should also know how to exhibit the results of experiments graphically and how to make deductions from graphs, e.g. from intercepts and gradient in the case of straight-line graphs, deductions by interpolation. Ac Servo Motor
Candidates will be expected to be conversant with SI units .”
These lines clearly direct the students and teachers towards the right approach to getting high grades in this subject. To know the syllabus continue reading.
There will be two papers in the subject:
Paper I - Theory: 3 hours…… 80 Marks
Paper II - Project Work ……. 20 Marks
Paper I (Theory): 80 Marks
The paper will be divided into two parts.
Part I: will consist of short answer questions. This part will be compulsory.
Part II: will consist of eight questions. Candidates will be required to answer five questions.
PAPER II (PROJECT WORK): 20 Marks
In addition to the syllabus prescribed above, candidates are also required to be assessed in Project Work. The Project work will be assessed by the subject teacher and the Visiting Examiner appointed locally and approved by the Council.
All candidates will be required to have completed two projects from any topic/s covered in theory.
Mark allocation for each project (10 marks) *:
List of suggested assignments for Project Work:
