Teaching-Learning Methodology
Topics are taught using interactive lectures, real instrument demonstrations, and videos. Every concept is linked to a biomedical instrument or agricultural device the student will encounter in their career. Simple calculations are preferred over derivations.
Falstad/Tinkercad simulations are used to visualise circuit behaviour.
