Linear and Non Linear Resistors

Linear resistors are those in which current produced is directly proportional to the applied voltage. Their current versus applied voltage is straight and linear. In other words, their resistance remains constant. Non-Linear resistors are those...

Chemical Vapor Deposition (CVD) Diamonds

Chemical Vapor Deposition (CVD) is a process used to make a very pure high performance solid material. It is the same thin film process that is often used in the semiconductor industry. In the case of CVD diamonds, this process is used with carbon...

What Are Force Sensors And How Are They Used

According to Wikipedia, the general definition of a transducer is a device that converts an applied energy directly into another form of energy. The force sensor is a particular form of transducer that...

Electrical components

Resistors and Potentiometer The purpose of this section is to provide the reader with a basic concept of the physical structure of resistors and potentiometer, and how to determine their values. Resistors Figure 1 shows a simple resistor. A...

Surface Mount Components

Electronic surface mount components are attached directly to the printed circuit board (PCB). They are also known as SMT components (surface mount technology) or SMD (surface mount devices). These components can be either active or passive...

How Big a Resistor Does An LED Need

Suppose that we're use the Vishay LED. Remember its requirements from the data sheet? Maximum of 3 volts, and a safe current of 20mA. I'm going to limit it to 2.5 volts, to be on the safe side. We have 6 volts of battery power. Subtract 2.5 from...

How I was taught to remember the resistor color code

Potentiometers

Potentiometers, often referred to as "pots", are considered to be a passive electronic component. They are, in fact, a type of resistor. To be more precise, they are a three terminal variable resistor. Unlike a fixed resistor, that has a...

How to Replace Light Bulbs with LEDs

LEDs are often far brighter than regular incandescent light bulbs. LEDs, such as this one pictured above, can become very hot. This particular one is being fed 4.5 watts, most of which is being converted to...
