OEF ohm --- Introduction ---

This module actually contains 9 computational exercises on ohm's law and serial and parallel connections of electric resistors. Each exercise corresponds to a type of circuit; you can choose the style of questions to ask for the circuit. It is also possible to choose several types and styles for the software to make random mixes.

Don't forget the chronometer which, combined with a large error tolerance, is an ideal tool for practising with mental computations.
