What is the difference between MOSFET and HEMT?
In this topics we will understand what is difference between MOSFET and HEMT? Defination and use of Mosfet Mosfet (metal-oxide semiconductor field-effect transistor, pronounced maws-feht) is a special type of field-effect…
What is pinch voltage?
When the gate voltage (-vgs) is made more negative, the channel width decreases until no more current flows between channels and the source is said to be pinched (similar to…
How does AC work? Does this mean the electrons swing back and forth along the wire at the frequency of the current flowing?
The ac current does not flow in the same direction. electrons in the wire (and other components) simply move back and forth. You know a joke where everyone is lining…
How does the diode work?
When we talk about electrical and electronic circuits, we use the old convention, called the conventional current flow (from positive to negative). To get rid of any idea of thinking…
Why zener diode is used?
Zener diodes are widely used as voltage references and as shunt controllers to adjust voltage across small circuits. When connected in parallel with a variable voltage source so it is…
What is the replacement scheme used in ac voltage regulator using TRIAC? How?
replacement scheme used in ac voltage regulator using TRIAC. An ac voltage controller is used to vary the rms value of the alternating voltage applied to the load circuit by…
Relationship of Voltage, Current, and Resistance
Relationship of Voltage, Current, and Resistance All circuits are a combination of three electrical properties: voltage, current and Resistance. Voltage is defined as the force that causes free electrons to…
Effects of Current Flow
The current flow has four effects that are used in different ways: magnetism, heat, chemistry Action and physical shock. Magnetism When current flows in a conductor, it creates a magnetic…
How do photodiode arrays work?
Working of photodiode How does photodiode work : A photodiode array (PDA) is a linear range of discrete photodiodes on an integrated circuit (IC). For spectroscopy it is placed at…
