Electric paint provides a great platform for discovering, laying, repairing and designing with electronics. Electric Paint can be used as both a liquid wire and a conductive adhesive or cold solder.
This handy pen allows you to draw circuits and attach small components to your projects. E...
A moving coil voltmeter, suitable only for d.c. voltages. Sensitivity 1000Ω/V nominal. Ranges 5V and 15V.
A centre zero galvanometer 50μA - 0 - 50μA graduated every 2μA.
The resistance of the meter is about 1000?.
This moving coil meter has two ranges, 0 to 1A or 0 to 5A and is suitable for d.c. only. Volts drop 75mV.
The National Grid Demonstration is an extremely safe way to demonstrate the advantages of distributing power at high voltages.
The demonstration is made up of two step up/down transformers that are used to transform the 12V ac from a school power supply to 115V (nominal). The trans...
This kit provides everything required to produce a simple d.c. motor, helping students to better understand how they work and the principles behind them. Fully illustrated instructions make building the motor an accessible project for students of all levels.
The kit contains:

Comparisons can be made between the AA and D cells - internal resistance and maximum current.
It is hoped that students will see patterns - smaller resistors result in smaller terminal voltage and larger circuit currents.
Your ammeter should be connected between point X and the top of...
