Alternating Current Notes

Higher Secondary is the most crucial stage of school education because at this juncture specialized discipline based, content  ‐oriented courses are introduced. Students reach this stage after 10 years of general education and opt for Chemistry/Physics with a purpose of pursuing their career in basic sciences or professional courses like medicine, engineering, technology and study courses in applied areas of science and technology at tertiary level. Therefore, there is a need to provide learners with sufficient conceptual background of Chemistry/Physics, which will make them competent to meet the challenges of academic and professional courses after the senior secondary stage.
