Different types of rectifiers and their applications in daily life

What is Rectification? Conversion of alternating current into direct current is called rectification. Semiconductor diodes are extensively used for this purpose. How many types of rectification ? There are three common types of rectification: Half wave rectification Full wave rectification Full Wave Bridge Rectification Voltage multipliers rectification Half Wave Rectification An alternating voltage of Time period T is called input ...

Kirchhoff’s voltage and current law with examples

What is Kirchhoff’s Voltage Law? Kirchhoff’s voltage law is a fundamental circuit law that states that the algebraic sum of all the voltages around a closed path is zero or, in other words,the sum of the voltage drops equals the total source voltage. Kirchhoff’s loop rule In an electric circuit, the voltages across the resistors(voltage drops) always have polarities opposite ...

Types of logic gates

Logic gates are electronic circuits that makes logic decisions.It has one output and one or more inputs. Output signal appears only for certain combinations of input signals. Logic gates are the building blocks from which most of the digital systems are built up. They implement the hardware logic function based on the logic algebra developed by George Boole, that is ...

Photodiode applications with working and uses

What is Photodiode? The photo diode is the device which operates in reverse bias.The photo diode has small transparent window that allows light to strike the pn junction. Photodiode working We know that when reverse biased ,the rectifier diode has a very small leakage of current.The same is true for photodiode.The reverse biased current is produced by thermally generated electron ...

Difference between astable monostable and bistable multivibrator

what is multivibrator? The name mutivibrator designates a group of the circuits widely applied for switching as shift registers or temporary memories and as square were timing oscillator or clocks. These circuits are basically closed loop feedback circuits operating with the feedback. Types of multivibrators There are three general types of multivibrators, which are: The astable or free running mutivibrator ...

Difference between forward and reverse biasing of semiconductor diode

The difference between forward bias and reverse bias is that in forward biasing positive terminal of the battery is connected with p-type and negative terminal is connected with n-type of semiconductor,while in reverse biasing positive terminal of battery is connected with n-type and negative terminal is connected with p-type. The bias a diode,you apply a dc voltage across it. Forward ...

what is the difference between p type and n type semiconductors?

Difference between n type and p type semiconductors Depending on the type of doping material used ,extrinsic semiconductors can be further subdivided into two classes: N- type semiconductors P-type semiconductors N-type semiconductors This type of semiconductor is obtained when a pentavalent material like antimony (Sb) is added to pure germanium crystal.fig Each antimony atom forms covalent bonds with the surrounding ...

Difference between conductors and insulators with examples

The difference between conductors and insulators is that conductors are those materials that conducts electric current easily while insulators are those materials which do not conduct current easily. Conductors A conductor is a material that easily conducts electrical current.Most metals are good conductors.The best conductors are single element materials,such as copper(Cu),silver(Ag),gold(Au),which are characterized by atoms with only one valence electron ...

what is difference between impedence and reactance?

Circuits with capacitors and inductors are more complicated than the resistive circuits we talked about earlier ,in that their behavior depends on frequency:A “voltage divider ” containing a capacitor or inductor will have a frequency dependent division ratio.In addition ,circuits containing these components (known collectively as reactive components),”corrupt” input waveforms such as square waves,as we just saw. However,both capacitors and ...
