Transistors are electronic devices used to amplify or switch electronic signals and power.

• Transistors are made of semiconductor materials like silicon or germanium.

• They have three terminals - emitter, base, and collector.

• Transistors can be used as amplifiers to increase the strength of a signal.

• They can also be used as switches to turn a signal on or off.

• Examples of transistor-based devices include computers, radios, and televisions.

Transistors are electronic devices used for amplification and switching. Some types include BJT, MOSFET, JFET, and IGBT.

• BJT (Bipolar Junction Transistor) - used in amplifiers, switches, and oscillators

• MOSFET (Metal Oxide Semiconductor Field Effect Transistor) - used in power electronics, digital circuits, and amplifiers

• JFET (Junction Field Effect Transistor) - used in low-noise amplifiers and voltage-controlled resistors

• IGBT (Insulated Gate Bipolar Transistor) - used in high-...read more

4-20 mA signal is preferred over 0-20 mA signal due to its ability to detect faults and provide a clear zero point.

• 4-20 mA signal has a clear zero point, making it easier to detect faults in the system.

• It allows for a wider range of measurement values, as the 0-4 mA range can be used to indicate faults or out-of-range conditions.

• 4-20 mA signal is less susceptible to noise and interference compared to 0-20 mA signal.

• It is a standard signal used in many industrial applications,...read more
