The Component Investigations Board has a selection of five different electrical components suitable for investigating current and voltage characteristics.  The board is easy to connect and use and is ideal for student use in the classroom. 

The Component Investigations Board contains the following clearly labelled components:

• Bulb,
• Resistor,
• Silicon Diode,
• Zener Diode,
• LED 

The Component Investigation board is an ideal resource to use with the Philip Harris Component Tester (B8R07108). 

Typical VI Graphs which were produced using the Philip Harris Component Investigations board and the Philip Harris Component Tester can be found in the Documents Section.
