For glass cutting, three rectangular glass pieces may be cut to make a kaleidoscope using a black

colour diamond cutter, or similar other components may be made.

Electrical & Electronics (8 hours)

Familiarization with LT switchgear elements, making its sketches and noting down its

specification. Kitkat fuse, Glass cartridge fuse, Plastic fuse holders (optional), Iron clad isolators,

MCB style isolators, Single phase MCB, Single-phase wire, wiring cable.

Demonstration of domestic wiring involving two MCB, two piano key switches, one incandescent

lamp, one LED lamp and plug point.

Simple wiring exercise to be executed to understand the basic electrical circuit.

Simple soldering exercises to be executed to understand the basic process of soldering.

Fabrication of a single-phase full wave rectifier with a step down transformer using four diodes

and electrolytic capacitor and to find its volt-ampere characteristics to understand basic electronic

circuit fabrication.

Examinations could involve the actual fabrication of simple components, utilizing one or more of the

techniques covered above.
