We have been supplying schools and colleges for 31 years and are highly experienced in the education sector. All schools have automatic account facilities. You can send an official school order by post, Fax or email. If you would like to order online please contact us in advance so that you can take advantage of education prices.

Our project kits are designed by teachers for use in the classroom. Our worksheets and projects are written by teachers and are used in classrooms daily to teach electronics.

We supply a vast range of components and actually hold stock. Over 95% of all orders received are shipped from stock.

One major difference between Electron and all the other component suppliers to the education sector is that we offer ALL schools and colleges what is known in the industry as last column pricing. Just look for our last price break, this is the price every school in the UK will pay regardless of how many or how few you order. Schools and Colleges no longer have to buy in large quantities to obtain the lowest prices.

Our new e-textiles catalogue can now be downloaded in colour. It includes the DaisyPIC range of projects, a selection of LED's, conductive thread, solder paste and tools to aid production.

Resistor colour code

Resistors are found in almost every electronic circuit. Being able to identify the value of a resistor from its colour bands is an essential part of electronics. An incorrect value resistor in a circuit could have devastating results. This worksheet introduces the beginner to calculating the value from the colours and the colours from the value. Ideal for KS3 and KS4.

Measuring Resistors

This worksheet is designed for a practical lesson where students have to record the actual colours on real resistors and then work out the value of the resistor. Resistor measuring

Resistors in Series and Parallel

Resistors are often connected in series or parallel within circuits. Being able to calculate the total resistance of either a series or parallel circuit challenges students with some simple mathermatical calculations. This worksheet provides questions on Series, Parallel and potential divider circuits and should be used in conjunction with our book Understanding Electronics

Preferred Resistor value

Resistors are not manufactured in every value from 1R to 1M Ohms. Instead manufacturers devised preferred resistor values. Popular ranges include the E12 and E24 series. This worksheet provides questions where the student has to work out the next value available from the one given. In the next set of questions the student will have to choose a suitable resistor value as the one given lies between two values.

Circuit symbols

Being able to recognise component symbols is an important part of basic electronics. This worksheet has a number of common symbols including resistors, capacitors, Logic gates and many more.

Understanding Electronics

To many people the word Electronics makes one feel that it is a complicated and difficult subject. Many books have been written on the subject but most tend to be too technical. In a moment of frustration at the lack of a simple book to aid his students, the author an experienced teacher of GCSE Electronic Products decided to write his own.

The book covers Basic electrical principles, Resistors (series, parallel, colour code, preferred resistors), Capacitors, Transistors, Logic Gates, Op-amps, Monostable and Astable timers

Electronics Revision questions

One of the best ways to prepare for examinations is to practice past exam questions. This prepares the student in understanding how questions are written and presented in exams as well as giving practice in answering them. This book was written by Noel Humphrey and is based on exam style questions from simple resistor colour code, to PICs and designing cases. It can also be used for setting cover work.
