As we said last month, electrical theory underlies everything we do in the electrical construction business. It is therefore necessary to review this theory regularly. We continue now with Ohm's Law.

THE first difficulty with this text is its title ; the A author has gone so thoroughly into basic circuit theory that the term 'elementary' cannot be justified. A considerable experience of elementary ...

The flow of electric charge lies at the heart of electronic circuits. However, electrons also have spin, and flows of electron spin play a vital role in spintronic circuits. These could be essential ...
