Technical data

What does the UI characteristic of an LED look like?

Item No. P1419301

Principle

Because stray light cannot enter the LED on account of the tube, this experiment can also be carried out in daylight. In this experiment you will learn to record a characteristic and to interpret it.

Benefits

Specified for the requirements of the german final secondary-school examinations
Especially for secondary schools
Quantum and wave optics in a student experiment

Tasks

What does the UI characteristic of an LED look like? A light emitting diode (LED) is a semiconductor component which has a characteristic curve. A component can be caharacterised by the relationship between the applied voltage and the measured current.
