Resistivity of Chemical Elements

A resistividade elétrica, resistência elétrica ou resistividade é simplesmente uma característica específica de cada material que define o quanto ele se opõe à passagem de uma corrente elétrica. Abaixo uma tabela periódica com a resistividade elétrica dos elementos químicos. Resistividade Elétrica dos Elementos Químicos Salvar

O que são Componentes Passivos

passive components

Os componentes eletrônicos podem ser passivos ou ativos, os componentes passivos são os componentes eletrônicos que não aumentam a intensidade de uma corrente ou tensão de um circuito. Eles são também chamados de componentes básicos. Há quatro grandezas físicas de interesse para a eletrônica que são: voltage, flow, carga e corrente. Duas das grandezas físicas são definidos em termos das outras duas. (Atual é ...

Grandesas Elétricas – Volts – Ampere – Ohms e Watts

Symbols AC and DC

I'm starting to write an e-book in which I intend to teach basic electronics who is starting. I'll try to use simple language to try to achieve those users without affinity with the area. It will not be like any electronics course Senai, will not delve, but to give a basic understanding, enabling any user to understand a little electro-electronic, ...

Simple Storage System Resistors

Simple Storage System Resistors

  This is a pretty cool idea and simple to store Resistors orderly. I usually use plastic pots, used in these mayonnaise, but this idea of ​​using Ziploc bags as binder, makes it much easier to find the resistor value and also their storage. The advantage is that you can organize your resistors ...
