The decimal number system comprises of digits from 0-9 i.e. 0, 1, 2, 3, 4, 5, 6, 7, 8 & 9. The base or radix of the decimal number system is 10 because total number of digits available in decimal number system is 10. It doesn’t imply that these 10 digits will represent only 10 quantities, but all the other digits can be expressed with the help of these numbers. Decimal number system is the most common number system which we use in our daily lives. If we want to deal with digital system … [Read more...] about Decimal Number System
Kirchhoff’s Law
Have you ever thought why we need a Kirchhoff’s Circuit law? Your answer might be that Kirchhoff’s Circuit law is used to find current and voltage in electronic circuits but then what about Ohm’s law? Because Ohm’s law can also be used to determine current and voltage in electronic circuits, but still we need Kirchhoff’s circuit law, why is it so? The answer to this question is, in the case of complicated circuits such as Bridge and T-networks we cannot find current and voltage circulating in … [Read more...] about Kirchhoff’s Law
Number System
Computers understand machine language. Every letter, symbol etc. that we write in the instructions given to computer, it gets converted into machine language. This machine language comprises of numbers. In order to understand the language used by computers and other digital system it is crucial to have a better understanding of number system. Number systems can be classified into its sub-types on the basis of base of that system. Base of a number systems plays crucial role in understanding … [Read more...] about Number System
Electronic Components
Definition: Electronic components are the elements of circuit which helps in its functioning. They can be classified into two types i.e. Active Components and Passive Components. Active elements are those which possess gain. They can give energy to the circuit. On the contrary passive elements do not possess gain and they cannot give energy continuously to the circuit. Passive components cannot amplify or energize the energy of the signal associated with them, they can only attenuate it, … [Read more...] about Electronic Components
Hall Effect Sensor
Definition: Hall Effect Sensor is the solid state device which switches to active state when it is introduced in magnetic field. The output voltage of hall effect sensor is dependent on magnetic field around it. When the magnetic field across the semiconductor slab changes the magnetic flux density also changes due to which the output voltage of hall effect sensor varies. Principle of Hall Effect Sensor The hall effect sensor works on the principle of hall effect. According to hall effect … [Read more...] about Hall Effect Sensor
Digital Electronics
Definition: Digital Electronics is the sub-branch of electronics that deals with digital signals for processing and controlling various systems and sub-systems. In various applications like sensors and actuators, usage of digital electronics is increasing extensively. Digital Signals Digital electronics is entirely the field in which digital signals is used. Digital signals are discretization of analog signals. A signal carries information. In digital signals, the values in a particular band … [Read more...] about Digital Electronics
Hall Effect
Definition: When a piece of metal or semiconductor is placed in magnetic field, more precisely in transverse magnetic field, and direct current is allowed to pass through it, then the electric field gets developed across the edges of metal or semiconductor specimen. This phenomenon is called Hall Effect. Explanation of Hall Effect Consider a piece of metal is placed in magnetic field. And the magnetic field is perpendicular to the metal or semiconductor specimen. Now, direct current is passed … [Read more...] about Hall Effect
Surge Protector
Definition: Surge Protector is a resistor which is inserted between rectifier circuit and the filter circuit to prevent the circuit from surge current. In general applications it may be omitted but in case of power supply it is beneficial to use surge protector or surge resistor. You may be thinking that why we have introduced a new term here i.e. Surge Current. As we have not used this term in our previous articles. So, surge current is the peak current which flows during initial … [Read more...] about Surge Protector
3 Phase Rectifier
Definition: A 3 Phase rectifier is a device which rectifies the input AC voltage with the use of 3 phase transformer and 3 diodes which are connected to each of the three phases of transformer secondary winding. Significance of 3 Phase Rectifier A single phase rectifier also rectifies i.e. converts AC supply to DC supply but uses only single phase of transformer secondary coil for the conversion. And the diodes are connected to the secondary winding of single phase transformer. The drawback … [Read more...] about 3 Phase Rectifier
Voltage Doubler
The voltage doubler is a device which delivers double the peak voltage (maximum voltage). It comprises of capacitor filter circuit which delivers double DC voltage of the peak input AC voltage. Voltage doublers are of significant importance in devices which needs high voltage and low current. Some of the devices which fall in this category are cathode ray oscilloscopes, picture tube used in TV receivers and in the display of a computer. Half - Wave Voltage Doubler The half wave voltage doubler … [Read more...] about Voltage Doubler
