Equipment / Software Required

Experimental set-up, inbuilt assembly or specific experiment related apparatus and manuals etc.
Light sources, multimeters, rheostat, keys and other required materials.

Teaching-Learning Methodology

Each laboratory session begins with a brief pre-lab discussion connecting the experiment to the corresponding objectives. Students write an aim, apparatus list, procedure, observation table, calculations, result, and inference. Post-lab discussion sessions relate experimental findings to real-world engineering applications. Students maintain a laboratory record book assessed for viva, record, and observation components.
