ISC Class 11 Electricity and Electronics Syllabus 2024: Read the article to have the updated ISC Class 11 syllabus for Electricity and Electronics. The syllabus provided in this story is CISCE formulated with step-wise elaboration. Download the 2023-24 syllabus pdf as well.
Class 11 2023-24 Electricity and Electronics syllabus ISC: CISCE, the Council for the Indian School Certificate Examinations is an educational board that serves the purpose of delivering education to students at the national level. This education board organise and cover ICSE and ISC examinations. ISC is for Class 11 and Class 12. This article is to explain the Electricity and Electronics syllabus Class 11 ISC. The subject code is 866. Unlike other syllabi, CISCE hasn’t mentioned any direct aims for this subject but it says “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.
Candidates will be expected to be conversant with SI units.”
Hope you have understood the words of CISCE mentioned for the ISC Class 11 Electricity and Electronics syllabus 2023-24. Now it’s time to discuss the syllabus in detail. Let us start with key highlights.
ISC Class 11 Electricity and Electronics Syllabus Key Highlights
