What Is the Richardson’s Equation Kit Used For?
The work function is the minimum energy an electron needs to escape from a metal surface. Richardson’s equation links the saturation current emitted by a hot cathode to its temperature and work function, so measuring the saturated plate current of a diode at several cathode temperatures and plotting the logarithm of the current divided by the temperature squared against the reciprocal of temperature gives a straight line whose slope yields the work function. This is a standard B.Sc. physics practical on thermionic emission. Change the cathode temperature in small steps, let the readings settle at each setting, and keep the valve upright and protected from knocks.
Frequently Asked Questions
What does the kit include?
According to the listing it is complete with a power supply, three meters and a diode valve, with the circuit diagram printed on the front panel. Ask JLab for the meter ranges and supply ratings with your quotation; they are not given in the listing.
How is it different from the Diode Valve Characteristics Apparatus?
That separate unit plots the plate V–I characteristic of a diode valve; this kit is intended for the work-function experiment based on Richardson’s equation.
Who manufactures this kit?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a physics laboratory equipment manufacturer in India incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The kit is made in its own works, not bought from a trader, so colleges, dealers and importers order factory-direct, each kit is visually inspected before dispatch, and repeat orders are handled by the manufacturer. JLab is registered as a manufacturing enterprise under MSME Udyam number UDYAM-HR-01-0003849 and exports using Importer-Exporter Code 3317504552. JLab exports worldwide and ships to buyers in every region — for example Sri Lanka in South Asia, Australia in Oceania, Mexico in North America, Hong Kong in East Asia and Kazakhstan in Central Asia.
