Reading time: <1 minut The Breadboard or Protoboard is a prototyping space generally used for the quick and easy realization of a circuit without the need to glue the wires. Breadboard applications are many, being recommended when you start learning electronics.
Reading time: <1 minut This course presents interactively general aspects described for everyone to understand, regarding the connection of batteries in electronic circuits, experiments with series and parallel circuits, how to read and operate resistors, how to operate and place LEDs in circuits electronics, how NPN transistors work, electrolytic capacitors and more.
Reading time: 2 minute Cells, also called photovoltaic cells, usually have a very small surface area and the current generated by a single cell is small but series, parallel combinations of these cells can produce currents large enough to be used in practice.
Reading time: <1 minut Distortion and noise are two different unwanted effects on signals. The systems are designed to minimize the effect of these two unwanted phenomena. In data communication, if not properly addressed, the effects of attenuation and distortion have the potential to make a data transfer unsuccessful.
Reading time: <1 minut The MOS (Metal Oxide Semiconductor) transistor is a semiconductor device, made of silicon, which has three terminals, called DRAIN, GRID, and SOURCE. Depending on its constructive peculiarities, MOS transistors are divided into two main categories: MOS transistors with induced channel and MOS transistors with initial channel.
Reading time: 2 minute Among the main topics discussed in this course, we list: Measurements on the shape of signals; Distortion meters with filters; Sensors-execution elements; Metrological characteristics of transducers; Input impedance, output impedance and load effect; Temperature measurement methods; Methods based on infrared radiation absorption; Ionizing radiation dosimetry.
Reading time: 2 minute After an introduction in the field, the main elements that intervene in the measurement of some electrical quantities are presented, namely: the measuring device, the unit of measurement, the measurement method, the measuring means, the standard.
Reading time: 2 minute Passive components consume the energy of electrical signals but are necessary in the operation of all circuits, because they provide voltages and currents at different points, regulate power levels, delimit its frequency bands.
Reading time: 2 minute The course refers to the controlled static converters which are built with controlled semiconductor elements and which, in addition to converting electricity, allow the control of the average power transmitted to the load.
Reading time: 2 minute The course presented is structured in 8 chapters as follows: Introductory notions; Voltage and current sources; Semiconductor diodes; Bipolar transistors; Recovery and stabilization; Devices with negative dynamic resistance; Field effect transistors; The effect of temperature on characteristics.
