A transistor is a fundamental semiconductor device used to amplify or switch electronic signals. There are several types: BJT (Bipolar Junction Transistor) operates using both electrons and holes and is current-controlled. JFET (Junction Field Effect Transistor) is voltage-controlled and uses a reverse-biased gate to control current flow. MOSFET (Metal-Oxide-Semiconductor FET), widely used in digital and power electronics, offers high input impedance and fast switching. IGBT (Insulated Gate Bipo

Transistors come in various types, each suited for specific applications. BJTs (Bipolar Junction Transistors) use both electron and hole charge carriers and are great for amplification. JFETs (Junction Field Effect Transistors) control current with voltage applied to the gate and offer high input impedance. MOSFETs (Metal-Oxide-Semiconductor FETs) are widely used in switching and power electronics due to fast switching and low gate current. IGBTs (Insulated Gate Bipolar Transistors) combine the
