What are Micro-Electromechanical Systems (MEMS)?
MEMS stands for Micro Electromechanical System. It refers to high-tech devices with a size of several millimeters or even smaller. Its internal structure is generally in the micrometer or even nanometer level. It is an independent intelligent system. It is mainly composed of three parts: sensors, actuators, and micro-energy. MEMS involves multiple disciplines and engineering […]
What is a Rheostat?
A rheostat is a variable resistor which is used to control current. They are able to vary the resistance in a circuit without interruption. The construction is very similar to the construction of potentiometers. It uses only two connections, even when 3 terminals (as in a potentiometer) are present. The first connection is made to […]
What is Microelectronics?
Microelectronics is a subfield of electronics that studies tiny complex machines or micro-chips that allow most of our devices to function, such as our cellphones. A microprocessor is a microchip. It is crucial in the field of microelectronics with billions of transistors per square centimeter, amplifying, controlling, and generating electrical signals. These transistors function as on and off […]
How Does the Resistor Color Code Work?
Resistor values are often indicated with color codes. Practically all leaded resistors with a power rating up to one watt are marked with color bands. The coding is defined in the international standard IEC60062. This standard describes the marking codes for resistors and capacitors. In addition to defining the color bands, the standard also includes […]
