Activity : To measure e/m of Electron by Thomson Method Bar Magnet method. One method of demonstration modern physics in the controlled bending of stream of high speed electrons in a magnetic field. The actual measurement by students of the ratio of the charge on the electron to its equally minute mass imparts a stimulating sense of achievement. e/m apparatus has been perfected to the point where it is possible for this fundamentally important measurement to be carried out with good accuracy. Power Supply : E.H.T. 800V D.C. for cathode Voltage to C.R. tube. 0-100 volts D.C. with moving coil meters to measure the Deflecting voltage either y1 or y2 Plates. Cathode Ray tube fitted on wooden frame with scale divided in centimeters. Deflecting Magnetometer with permanent magnetic compass included. Compass stand, a pair of Bar Magnet.

The noted oil drop experment by which Prof. Robert A. Millikan measured the charge on the electron can be repeated by the student with this equipment. The latest improved design is based upon the experience and recommendation of teachers. Principal elements of the assembly are specially designed condenser, a light source and a measuring microscope. The All are mounted on a common support. Consisting of a heavy cast iron base which is mounted on a steel pillar that carries the microscope and the lamp house. The microscope can be adjustedsmoothly by slow motion screws in the horizontal as well as in the vertical direction. Atomizer is also fitted on the same carriage. The apparatus does not need any critical adjustment and the oil drops appear in microscope within seconds. Microscope is provided with micro meter scale.

Specially designed for use with Millikan's Oil Drop Apparatus. It give IC regulated D.C. output 0.300 volt continuously variable to be applied to condenser plates and a 6 volt at 3A A.C. supply for the lamp house.

Having three major parts to measure electron for e/m by Helical Method, i.e.

Kit is based on 8085 Microprocessor and is designed to provide ease in interaction with 8 bit Microprocessor capabilities. This Kit can be used to train engineers about the Microprocessor Technology, to control any Industrial process and to develop Software for 8085 system. This Kit has a powerful monitor in 4/8 bytes EPROM. The monitor can be extended to incorporate an Assembler and Dissembler for 8085. The Input/Output structure includes programmable 241/O lines. It has got 16 bit programmable Timber/Counter using 8253 for generation of any type of counting. Different types of INTERFACING MODULES from us can be hooked with this kit to perform simple experiments & projects in the lab. These modules are very helpful in learning about the real time inter acing problems of microprocessor.
