How does a capacitor work for both AC and DC ?
A capacitor operates differently depending on whether it is used in an AC (alternating current) or DC (direct current) circuit,…
Can capacitors store AC power ?
Capacitors cannot store AC power in the same way they store DC power. Capacitors store energy in an electric field…
Why does photo diode conduct in reverse bias while all other diodes conduct in forward bias ?
A photodiode conducts in reverse bias because, under reverse bias, it is sensitive to light. When the photodiode is exposed…
How to choose a MOSFET ?
Choosing the right MOSFET involves considering several key factors to ensure it meets the requirements of the circuit or application:…
What are NPN and PNP diodes How do they work ?
Diodes are semiconductor devices that allow current to flow in one direction only. NPN (Negative-Positive-Negative) and PNP (Positive-Negative-Positive) are types…
Whats the difference between JFET and MOSFET ?
The main difference between a JFET (Junction Field-Effect Transistor) and a MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) lies in their construction and…
What is the difference between a fuse and a circuit breaker?
A fuse and a circuit breaker both serve the purpose of protecting electrical circuits from overcurrent situations, but they operate…
Does a transistor amplify current or voltage ?
A transistor can amplify both current and voltage, depending on its configuration and how it is biased in a circuit….
Why are transistors called transistors ?
The term “transistor” is a combination of “transfer” and “resistor,” reflecting its function as a device that transfers electrical signals…
Relationship of Voltage, Current, and Resistance
The relationship between voltage (V), current (I), and resistance (R) is governed by Ohm’s Law, which states that V =…
