AI is growing fast. It writes, designs, and solves problems. But some creative powers still belong only to humans. Here are six skills where imagination wins over machines. The magic of storytelling Stories carry emotion. They connect people and spark feelings. From novels to films, real storytelling comes from imagination and empathy—things AI cannot feel. … Read more
What is a load resistor and why is it used ? A load resistor is a resistor that is specifically used to simulate an electrical load in a circuit. It is employed to ensure that the circuit operates correctly under load conditions, which can help in testing, designing, and analyzing circuits. Load resistors are crucial … Read more
How does a DC link work What is its purpose ? A DC link, in the context of power electronics and variable frequency drives (VFDs), refers to a crucial component that connects the rectifier and inverter sections of the drive. Its primary function is to smooth out the rectified AC voltage into a stable DC … Read more
What is the difference between enhancement and depletion Mosfet? A MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) operates in two primary modes: enhancement mode and depletion mode. Each mode serves distinct purposes and has unique characteristics. Enhancement Mode MOSFETs Enhancement mode MOSFETs require a positive voltage at the gate relative to the source to create a conductive channel … Read more
What is triode region in mosfet ? Triode Region in a MOSFET The triode region in a MOSFET refers to an operational mode where the transistor behaves similarly to a triode vacuum tube. In this region, the MOSFET exhibits a linear relationship between the drain current (I_D) and the drain-source voltage (V_DS), functioning like a … Read more
Difference between NMOS PMOS and CMOS transistors ? NMOS (N-channel Metal-Oxide-Semiconductor) and PMOS (P-channel Metal-Oxide-Semiconductor) are types of MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors) distinguished by their channel doping types. NMOS transistors feature an N-type channel (electron-conducting), while PMOS transistors have a P-type channel (hole-conducting). CMOS (Complementary Metal-Oxide-Semiconductor) technology integrates both NMOS and PMOS transistors in a … Read more
What is the pinch off voltage for a JFET? The pinch-off voltage in a JFET (Junction Field-Effect Transistor) refers to the gate-source voltage at which the channel between the source and drain becomes fully depleted of charge carriers (electrons or holes). At this point, the electric field created by the gate-source voltage effectively pinches off … Read more
Modes of Operation of MOSFET The Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) is one of the most widely used transistors in modern electronics due to its efficiency, high input impedance, and fast switching capabilities. The MOSFET operates in different modes depending on the applied voltage across its terminals: Source (S), Gate (G), and Drain (D). The behavior … Read more
How is FET a Voltage Controlled Device? The Field Effect Transistor (FET) is a type of transistor that operates primarily based on the electric field created by a voltage applied to its gate terminal, making it a voltage-controlled device. Unlike Bipolar Junction Transistors (BJTs), which are current-controlled devices, FETs rely on an electric field to … Read more
What happens to current when voltage is increased ? When voltage is increased in an electrical circuit, according to Ohm’s Law (V = IR), if the resistance (R) remains constant, the current (I) will increase proportionally. This means that as the voltage across a circuit or component increases, assuming the resistance stays the same, the … Read more
