What is Ohm’s law in simple words?
Ohm’s Law states that the current flowing through a conductor between two points is directly proportional to the voltage across…
Why transistor is so difficult to understand ?
Understanding transistors can be challenging for several reasons. Firstly, transistors operate based on principles of semiconductor physics, which involve complex…
What are MOSFETs ?
A MOSFET, or Metal-Oxide-Semiconductor Field-Effect Transistor, is a type of transistor that is widely used in electronics for switching and…
Why is a colour code used for resistors ?
A color code is used for resistors to indicate their resistance value, tolerance, and sometimes reliability or temperature coefficient. This…
Why does current lead voltage in a capacitor ?
In a capacitor, current leads voltage in AC circuits due to the phase relationship between the two. When an AC…
Why do we use biasing in transistor ?
Biasing in transistors is essential to establish the operating point or quiescent point (Q-point) where the transistor operates in its…
For what reason might one ever choose a JFET instead of a MOSFET ?
Engineers may opt for a Junction Field-Effect Transistor (JFET) over a Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) in certain applications for specific…
Why do we limit FET operation to small signals ?
FET operation is often limited to small signals to ensure linearity and prevent distortion. In small signal conditions, the FET…
Do resistors cause phase shift ?
Resistors do not cause phase shift in electrical signals. They are passive components that do not store energy in an…
Which are the best transistors CE CB or CC ?
The choice between common emitter (CE), common base (CB), and common collector (CC) transistor configurations depends largely on the specific…
