In electronics circuits, the signal is associated with an AC (Alternating current) and DC (Direct Current). The sinusoidal wave or sine wave represents the periodic AC signal that varies with time and fluctuates between positive and negative cycles. While DC signal/waveform represents the magnitude of voltage and current values easily and stable. But the magnitude of the current and voltage values of the AC signal should be calculated by using its instantaneous values, a peak value of the … [Read more...]
What is 7805 Voltage Regulator & Its Working
When there are fluctuations in the circuit, then the fixed output cannot be given by all voltage sources. To deal with this, a system is designed to maintain a constant voltage level automatically is Voltage Regulator. These voltage regulators are used in computer power supplies for stabilizing the DC voltages. Coming to power station generation plants and automobile alternators, the output is controlled by these voltage regulators. The regulation of one or more AC or DC voltages is done … [Read more...]
What is an Inductive Reactance : Formula & Its Working
An inductor is normally a coil of wire. When current is passing through that coil, the electric field will be generated. So the field will get induced. The induced filed depends on the number of turns and this is inductance. An inductor due to its inductance resists the flow of alternating current. Basing on the Lenz's law inductor will resist change in current. Reactance is defined as the resistance offered to the AC currents by capacitors and inductors only. Usually, reactance is denoted by X, … [Read more...]
What is an Open Loop Control System & Its Working
The collection of subsystems that controls the input signal to get the desired output is known as a system. The main function of any electronic system is regulating the output and keep that within systems desired input i.e when the input of the system changes, the output of the system should respond and change according to the changed input value. In another case, if there is no change in input but the output of the system is getting disturbed then the output should respond by coming back to its … [Read more...]
What is an ACSR Conductor & Its Working
A physical medium that carries electrical energy from one place to another place is known as a conductor. The minimum conductivity and tensile strength are important factors for transmission and distribution systems. In the earlier days, the copper conductors have used to transmit the energy. But now, these are replaced with stranded hard-drawn 1350 aluminum wires to increase the tensile strength, conductivity, and efficiency. The aluminum conductors are lightweight, economical in design, and … [Read more...]
What is Arduino Sensor : Types, Working and Applications
An electronic device that senses and responds quickly to physical changes such as distance, pressure, temperature, touch can be referred to as sensors. These are used commercially in various products for temperature monitoring, alarming circuits, and in the Home automation kits, etc... In the practical world, where the motive is to design a user-friendly environment such that various devices information can be controlled, sent, and monitored. This is made possible when the multiple sensors are … [Read more...]
What is a Latch : Different Types and Their Applications
The digital circuits made of logic gates as the basic devices. This leads to the formation of combination circuits and sequential circuits. The circuit design must have a memory element present in it. This element stores the data required for processing the code and the stored information is needed for the program during computing. The memories are treated as the key components in digital electronics. These storage devices are termed as a latch. Individual logic gates don't have any capability … [Read more...]
What is Carbon Composition Resistor & Its Working
In electronic circuits, resistors are the passive two-terminal devices used to regulate or reduce the flow of current in the circuit. Mostly fixed type resistors are used in the electronic circuits because of its fixed resistance value. The resistance is determined during the manufacturing process itself and it can't be varied like a variable type resistor. Based on the manufacturing process, the fixed type resistors are divided into 4 types such as carbon resistors, wire wound resistors, … [Read more...]
What is an Anemometer : Working & Its Applications
The first mechanical anemometer is invented by Leon Battista Alberti, who was an Italian artist and an architect in the year 1450. Later on, many changes are made and invented different types of anemometers to measure wind speed and pressure more accurately. The design and its working principle didn't change over hundreds of years. It is a meteorological device that can estimate whether conditions. These are used in many applications like monitoring the weather conditions, measure the air … [Read more...]
What is Metal Oxide Varistor & Its Working
A passive two-terminal semiconductor device that is used to protect electronic and electrical circuits is called Varistor. It protects against over-voltage by clamping of voltage. It is also known as a voltage dependant resistor (VDR) or non-linear resistor. The resistance of the varistor is changed due to the change in voltage across it. The varistors are non-ohmic variable resistors with symmetrical current and voltage features applicable for both DC and AC applications. In AC operations, … [Read more...]
