LDR (Light Dependent Resistor) Characteristics refer to the relationship between the resistance of an LDR and the intensity of light it is exposed to, typically showing a decrease in resistance as light intensity increases.

A 12kW loading rheostat is a variable resistor used to simulate electrical loads in testing or experimentation, allowing for precise control over power dissipation up to 12 kW.

A 50kW loading rheostat is a high-power variable resistor used to simulate electrical loads up to 50 kilowatts, typically employed in testing and evaluating power systems, generators, and electrical equipment under high-load conditions.

An Energy Band Gap Apparatus is used to determine the band gap energy of semiconductor materials by measuring their electrical properties under varying conditions.

An ointment spatula is a flat, smooth tool used for mixing, spreading, or applying ointments, creams, and other topical substances, ensuring hygienic and controlled application.

An ointment slab is a flat, smooth surface typically made of glass or porcelain, used for mixing and preparing ointments, creams, and other topical formulations in a controlled and hygienic manner.

A 6.5kW loading rheostat bank is a variable resistance system designed to simulate electrical loads up to 6.5 kilowatts, typically used for testing and maintaining power systems, generators, and other electrical equipment.

\n
• This is a simple, hand driven Van de Graaff generator designed to produce very high electric potentials at low currents.
\n
• The apparatus consists of a wooden base, an insulated Plexiglas stand, a rubber belt, a removable metal dome (135 mm diameter), a driving wheel, and a driving belt.
\n
• The discharge sphere, which has a diameter of 50 mm, is mounted on a pivoted arm that includes a handle for easy adjustment.
\n
• The length of the electrical spark is approximately 30 mm.
\n

\n
• Using a non-magnetic conductive tube, the Lazy Tube Kit demonstrates key physics concepts like Lenz's Law.
\n
• When a magnet is dropped through the tube, it creates magnetic forces that oppose the motion, visually showcasing Lenz's Law.
\n
• The Kit comprises two aluminium tubes, a plastic stand, one cylindrical magnet, and an iron cylinder.
\n

\n
• Four Stroke Diesel Engine Model ignition light and glow plug can be activated with a 1.5V AA Cell.
\n
• Hand crank operation demonstrates all the functioning stages of a 4 stroke diesel engine.
\n
• Made of durable cast alloys and ABS plastic for years of demonstrations.
\n

\n
• Newton Colour Disc Model demonstrates colour perception in humans.
\n
• It has coloured segments representing the primary colours of the spectrum, which blend together when rotated.
\n
• The eye perceives them as white light due to their sensitivity to colours in the middle of the spectrum.
\n
• The illusion of white light is created through the rotation of the disk.
\n

\n
• Our Domestic Circuit Apparatus helps students understand parallel connections commonly used in households.
\n
• Provides hands-on experience with the equipment and components that make up domestic circuits.
\n
• Specifically designed for 8-10th Class CBSE Syllabus
\n

\n
• The Primary colour shadow apparatus wooden box measures 6 x 6 x 3 inches and includes three LED lights, two wires, and a power supply board.
\n
• This apparatus demonstrates how objects can cast shadows with varying colours based on the light they block.
\n
• It demonstrates how we can make other colours using only red, green and blue.
\n

\n
• The reflection of Light Apparatus is designed to demonstrate the reflection of light in a plane mirror.
\n
• The setup includes a plane mirror mounted on a stable base, an adjustable light source, and a protractor or angle-measuring device.
\n
• The mirror's surface is precisely aligned to ensure accurate reflections.
\n
• The light source allows for controlled incidence angles, and the protractor measures the angle of incidence and reflection.
\n
• This apparatus visually confirms that the angle of incidence equals the angle of reflection, adhering to the laws of reflection.
