Exp-9 Characteristics of PN diode.
This centrifuge machine is equipped with
a clamp for mounting to a table 1 to 4 cm
thick. Made from enamel coated cast metal.
Holds centrifuge tubes up to 15ml in capacity.
The unit is approximately 30cm tall.
This clock keeps accurate time using energy from a battery that you make. Simply add weird liquids such as soda, fruit juice, dilute ketch-up, salt water, etc. to the two containers, insert four metal electrodes, and connect with three wires.
Exp- To measure the force required under static conditions to displace the mass the same distance against the pull of the spring.
Nature of primary & secondary colour may be shown using this apparatus. Colour mixing takes place when two or more colours come together to form a different colour. This apparatus demonstrates how different colours of light form - from the three primary colours. The three basic colours for mixing light are red, green & blue. There is a control box which controls the intensity of six numbers of LEDs (diodes) which are mounted on a stand. Additive and subtracting colour mixing are demonstrated on the screen.
