Voltamper LED characteristic
(approximate determination of Planck's constant)
Remote experiment
- Important:
- To start a remote control tasks must have your browser installed, and permitted some services. Before you start Make sure the processor so.
System requirements for remote start of the experiment:
- internet browser
with JavaScript and CSS (tested min. version: IE 5, FireFox 3.0, Opera 9.6, …)
- your internet browser MUST support AJAX (PC browsers are OK, but be careful for some SmartPhone)
- enable JavaScript in your Internet browser (instructions )
Control of the experiment
Adjust the el. voltage - the electric voltage can be adjusted by moving the slider or by buttons + and –
Experimental values - value of el. voltage on the diode and el. passing flow through the diode
Web camera - The camera shows five LEDs that are measured (selected LED will light up after crossing Up)
Writing values to the table - measured values are entered in a table of values
Table of experimental values - values of voltage and electric current is stored for plotting to the V-A characteristics
Work with data in Table - see chart, save data, delete table
