High Resistance Measurement by Leakage Method is useful for measuring very high value of Resistance. Digital Multimeters or LCR meters are used to measure the normal value of resistance (generally 1 Ω - 20M Ω) but in the case of very high value of resistance these are unable to measure with high accuracy.
Leakage method is very accurate way to measure the high value of resistance because of very sensitive ballistic galvanometer with scale & lamp arrangement and very low value of capacitances used in the product. It is provided with different values of unknown high resistances on rotary selection and different values of capacitors.Product Features

After experimental arrangement, the glass plate is inclined at an angle 45° to the horizontal.This glass plate reflects light from the source vertically downloads and falls normally on the convex lens. Newton's rings are seen using a long focus microscope, focussed on the air fil. The cross-wire of the microscope is made tangential to the 20th ring on the left side of the centre. The readings of the main scale and vernier scale of the microscope are noted. The cross wire is adjusted to be tangential to the 18th,16th, 14th etc on the left and 2nd, 4th, 6th etc on the right and readings are taken each time. From this the diameter of the ring is found out which is the difference between the readings on the left and right sides. The square of the diameter and hence Dn2 and D2n m are found out. Then wavelength is calulated using equatio.

Principle and Working :
Resolving power of a telescope is defined as the reciprocal of the smallest angle subtended at the objective lens of the telescope by two point objects which can be just distinguished as separate.
Resolving power of telescope is given by :
Resolving Power = D/d = a / 1.22 λ
Where, λ = 589 nm mean wavelength of light used
D = is distance of the objects from objective of the telescope.
d - is distance between two consecutive slits or objects
a - is critical width of the rectangular slit for just resolution of two slits or objects.
Exp-1 To determine the resolving power of a telescope.

In this experiment, the user will prepare a sugar solution of known concentration (c), but unknown identity. The user will obtain the observed rotation (αobs) from the experiment using the polarimeter and use that information to calculate the specific rotation [α] of the given sample using the above formula. The identity of the sample can thus be found out from the given list of specific rotations for different chemicals.
The procedure to perform this experiment is self-explanatory and leads the user in a step-by step manner to accomplish the task. The protocol briefly involves the following steps:
