Resistance Investigation Board

Resistance Investigation Board with 3 different types of wires

The Resistance Investigation Board allows you to study the dependence of the resistance on the length and diameter of the wire.

The device has three different wire samples with a diameter ratio of 1: 2: 4. They are placed between 4mm terminal sockets. The whole layout is on a wooden base with a length of 45cm.

The wire with the largest diameter is divided into 3 sections: 20cm, 8cm, 10cm. Between the sections there are the 4mm terminal sockets.

The wire with the intermediate diameter, has a length of 40cm.

The wire with the smallest diameter is placed in a section of 40cm. In that section, you can measure intermediate distances from 0 to 400mm.

In each wire (conductor) section there is an indication for maximum current (and power) that you can provide.

• 1.3A 4.5W MAX (for the wire with the largest diameter)
• 1A 4W MAX (for the wire with the intermediate diameter)
• 600mA 3W MAX (for the wire with the smallest diameter)

Dimensions of wooden base: 45x17cm
