This consists of two experiments: one where you will control a set of light sensors, and in the second take measurements on an experiment where a strain gauge forms one part of a wheatstone bridge.

OEL 2.1: Testing a real photodiode
In this activity you will experiment with data that you will collect from two photodiodes, one responding to visible light and the other responding to infrared light. The objective is to set resistor values so that the sensors have the widest possible range of values without becoming saturated.

OEL 2.2: Strain gauge experiment
In this activity you will set various parameters to investigate the behaviours of two strain gauges configured in different ways. By analysing voltage measurements from the two strain gauge circuits, you will be able to determine the value of the constant current being supplied.

Note that you will need to book a separate slot for each experiment.

The link to the booking system is below.

Please be aware that all bookings are in UK local time.

It is recommended you check the connection to the laboratory in good time before you attempt an experiment. This is particularly important if, for example, you change equipment, browser, location, or are accessing through a corporate network. To check your connection to the laboratory, please visit this link using the computer, browser, and network you intend using.

Recent changes to the Firefox and Chrome browsers to prevent nuisance advertisements mean that sound has to be turned off by default, otherwise the video content will not load automatically. Both sound and vision are seen as important to the laboratory experience, so we recommend that you turn up the volume once you have entered an experiment. You will find the Volume control at the bottom right of the Video panel.
