## Descrição Geral

For the correct understanding of electronics it is necessary to know some fundamental laws and theorems such as Ohm’s Law, Kirchhoff’s Laws and other simple theorems of initiation to D.C. circuits.

With Direct Current (D.C.) Circuits Module, "N-M1", designed by EDIBON, you can start to study the basic principles of direct current, such as:

• Handling of measuring and testing instruments (ammeter, voltmeter, ohmmeter and multimeter).
• Study of Ohm’s law and its practical testing.
• Study of the different resistors: electrical resistance, characteristics of resistors, study of the concept of resistivity, conductivity, conductance and how to measure resistors.
• Association of resistors (series, parallel, mixed circuit) and Wheatstone bridge.
• Study of Kirchhoff’s laws.

In addition, faults can be simulated in most of the study circuits. The student must investigate what is happening in the circuit and why it is not working correctly. These fault simulations can be of various types from faulty components to a hypothetical incorrect assembly of the circuit.
