2022/9/30
Looking at the schematic, VCC, VEE, VDD, and VSS are used for supply voltage. What is VCC, VEE, VDD, and VSS?What does the "CC" in "VCC" stand for?What does the "EE" in "VEE" stand for?What does the "DD" in "VDD" stand for?What does the "SS" in "VSS" stand for? This article explains the meaning and differences between VCC, VEE, VDD, and VSS. Meaning and Difference of VCC, VEE, VDD, and VSS The meanings and differences of VCC, VEE, VDD, and VSS used in the supply voltage are shown below. VCCVCC is used as the positive supply voltage for circuits using ...

: Electrostatic Induction (Explanation, Principle)
2022/9/21
Regarding the Electrostatic Induction, this article will explain the information below. Explanation of Electrostatic InductionPrinciple of Electrostatic Induction Electrostatic Induction Electrostatic induction is a phenomenon that occurs when a charged body is brought close to a conductor, causing a bias in the charge inside the conductor. Inside a conductor (a material that conducts electricity, such as a metal) are free electrons. Free electrons are electrons that can move freely inside the conductor and have a negative charge. Therefore, when a charged body is brought close to a conductor, the free electrons inside the conductor are subjected to electrostatic force and ...

: Dielectric Polarization (Explanation, Principle)
2022/9/21
Regarding the Dielectric Polarization, this article will explain the information below. Explanation of Dielectric PolarizationPrinciple of Dielectric Polarization Dielectric Polarization Dielectric polarization is a phenomenon that occurs when a charged body is brought close to an insulator, causing a bias in the charge inside the insulator. When a charged body is placed close to an insulator (a material that does not conduct electricity, such as an underlay), the electrons (which have a negative charge) in the molecules and atoms inside the insulator are subjected to electrostatic forces. The electrons inside the insulator are not free electrons that can move freely. ...

: Difference Between Through-hole, Blind Via, Buried Via, and Land
2022/9/14
What is the difference between through-hole, blind via, buried via, and land? Regarding the through-hole, blind via, buried via, and land, this article will explain the information below. Difference Between Through-hole, Blind Via, Buried Via, and Land Through-hole First, let us discuss through holes. A through-hole is a hole where the inner surface of a substrate hole is copper plated and electrically connected. There are two types of through holes as follows。 Through-hole for electronic componentsHoles through which terminals of electronic components are inserted for solderingVia holeA hole for the purpose of conduction between layers of a substrate pattern Next, ...

: Difference Between Transistor (MOSFET) and Relay
2022/9/14
Regarding the Transistor and Relay, this article will explain the information below. Difference Between Transistor and Relay Difference Between Transistor and Relay The figure above shows a transistor and a relay. A transistor (MOSFET) performs switching operations by applying a voltage to its gate terminal (G). On the other hand, a relay performs switching operations by electromagnetic force generated by passing current through a coil. Thus, transistor (MOSFET) and relay can be used as switches. So, what is the difference between a transistor (MOSFET) and a relay? We will now explain the difference between a "transistor (MOSFET)" and a "relay". ...
