In designing electrical circuits, the process of analyzing the circuit is a crucial part, which deals with voltage and current at each branch or node of the circuit. The process of analyzing the circuit is nothing but finding out the unknown voltage and current values of a branch or node. However, this process is complex because more components are connected together in the circuit. Hence the proper technique should be followed to determine the current and voltage. There are two possible … [Read more...]
What is a Flux Meter : Construction & Its Working
In electromagnetism, magnetic flux is defined as the number of magnetic lines of forces observed at the surface of a magnetic material. Magnetic flux is denoted with 'Φ'. The SI unit of magnetic flux is derived as volt-seconds, also known as Weber and Maxwell as CGS unit. To measure the amount of flux generated from a magnetic surface an instrument called 'Fluxmeter' is used. Fluxmeter consists of measuring coils placed between permanent magnets known as Helmholtz coil arrangement. The change in … [Read more...]
What is a Breadboard : Construction & Its Working
In the initial days of electronics manufacturing, engineers and designers have realized that sometimes designing a temporary circuit needs without soldering the components. So, an engineer took cardboard and arranged several rows into it to place nails. As per the circuit diagram, they placed components and nailed them through short wire pieces. The electrical connection can be provided by wrapping wire or soldering around the nails, and then components could be soldered to the wires. But by … [Read more...]
What are Network Devices : Types & Their Working
The development of computer networking started with the progress of Arpanet in the period of the ending of the 1960s and in the initial stages of the 1970s. Before the networking devices, there were computer vendor networks which are mainly constructed to associate connection between terminals and remote job entry locations with that of the mainframe. Whereas the crucial thought behind the networking was to accomplish network sharing and it was the basis in the ARPANET design. It is even more … [Read more...]
What is a Resistor Color Code & Its Calculation
Resistors are small electrical components, used in several electrical and electronic circuits to restrict the flow of current within the circuit and also to regenerate voltage drop in several ways. These are available in different sizes and shapes. Each resistor includes a resistance or resistive value that ranges from ohms to milliohms. So these values can be measured through the color band concept. For each small component, a color code is used to indicate the resistance value instead of … [Read more...]
What is Ferrite Bead : Types & Its Working
In various electronic circuits, ferrite bead inductors are used as an effective form of filter. A ferrite bead is made up of ferrite material in Halloween cylindrical shape. It is available in small sizes at affordable rates. It is also called a ferrite block, ferrite core or EMI filter, or ferrite choke or ferrite ring that is used to suppress high-frequency noise in the given electronic circuit. The properties of ferrite within the inductor might help to reduce EMI. The high permeability of … [Read more...]
What is a Resistor – Construction & Its Working
Resistors are essential components in electrical and electronic circuits which are used in different electronic devices. There are different types of resistors available but based on the type, their properties may vary. These properties will assist you while selecting the right type of resistor for designing any circuit. Different types of resistors are used in different applications based on the requirement. So it is compulsory to identify the type of resistor as well, in which the type of … [Read more...]
What is Distributed Control System : Working & Its Applications
In the initial days, the process of controlling for giant industrial purposes is so difficult and developed after multiple phases. Originally, the controlling requires panels for processing of plants and this needs a huge workforce too and even this provides no exact results. And the next advancement is the transformation of all plant measurements into a permanently controlled central room where acts as the centralism of entire localized panels providing the benefit of less workforce. But seems … [Read more...]
What is BCD Counter : Design & Its Operation
In the scope of digital logics, a counter is a tool that accumulates the information of how many times a specific process or event is occurring probably like a clock. The generally used type is a sequential digital logic circuit having an input line termed as a clock and has multiple output lines and the values those are on the output lines signify a number in the binary system. Every pulse that acts as input to the clock either increases or decreases the numbers count on the counter. With this … [Read more...]
Difference between Open Loop & Closed Loop Control System
In 1767, James Watt's Flyball governor invented a device called a control system to control the constant speed of the engine with the regulation of the speed of the steam supply to the engine. When the output of the system is regulated or controlled by varying the input, then such a type of system is called a control system. The function of the control system is determined by the differential equations (ordinary or difference equations). It can manage, command, direct and regulate the function … [Read more...]
