| Description |
Class set of 15 Capacitance Substitution Boxes. The IPC Capacitance Substitution Box (IPC-5861-X) provides the easily selection of 12 preferred value capacitors, ranging from 100pF to 0.47µF.
The values range from: 100pF, 220pF, 470pF, 1nF, 2n2, 4n7, 10nF, 22nF, 47nF, 0.1µF, 0.22µF and 0.47µF. All the capacitors offer a maximum voltage rating of 50V (AC or DC), with actual capacitance value tolerances of ±5% to ±10%. The unit is housed in a robust ABS plastic case with rotary selector switch and a pair of 4mm connection sockets.

BERT is a simple way of introducing electrical resistance and resistivity to a class. It consists of a circuit board that may be drawn on using the supplied pencil. Connecting the two sides of the board together by a pencil line gives a conducting track and the LED lights. The brightness of the LED gives an indication of the resistance of the path. Drawing the line thicker decreases the resistance, as does shortening the path. Resistances in parallel may be studied and a “volume control” simply made.
BERT may also be used to test various materials to see whether they are conductors or insulators. Liquids and pastes may also be tested. The conductivity of the class may be studied as well as how a switch works. When you are finished the pencil lines may be removed with the supplied eraser.

- Simulates resistances from 1Ω to 999,999Ω in 1Ω steps
- The required resistance is set by selecting the correct value from six rotary decade switches which clearly indicate the value selected by the student
- An additional 1kΩ resistor is provided connected between one of the terminals of the internal resistance and a third terminal so the unit can be used as an accurate potential divider
- All outputs are on 4mm terminals with 4mm sockets
- Housed in a tough ABS box with non-slip rubber feet
- Voltage rating 250V
- Power rating 600mW
- Dimensions 110 x 75 x 50mm
- Designed and manufactured in the UK
| Box mounted with 5 x 4mm sockets for attachment to an ammeter or voltmeter to display measurements. Monitoring the voltage of each LED a graph of energy input as a function of light frequency emitted can be measured with an approximate value of Plank's constant calculated.
- Supplied with 500 lines/mm diffraction grating
- Designed and manufactured in the UK
