Definition: The Parallel binary adder is a combinational circuit consists of various full adders in parallel structure so that when more than 1-bit numbers are to be added, then there can be full adder for every column for the addition. The number of full adders in a parallel binary adder depends on the number of bits present in the number for the addition. If 4-bits numbers are to be added, then there will be 4-full adder in the parallel binary adder. The parallel binary adder can be … [Read more...] about Parallel Binary Adder
Half Adder
Definition: Half Adder is the digital circuit which can generate the result of the addition of two 1-bit numbers. It consists of two input terminal through which 1-bit numbers can be given for processing. After this, the half adder generates the sum of the numbers and carry if present. It is very easy to guess the working of the adder just by its name. This is because the word adder consists of keyword “ADD” which means to add any numbers. But what does this keyword “HALF” signifies. You … [Read more...] about Half Adder
Cathode Ray Oscilloscope
Definition: The cathode ray oscilloscope is the instrument which generates the waveform of any electrical quantity. The waveform is generated in such a way that the amplitude of the signal is represented along Y-axis and the variation in the time is represented along X-axis. CRO is the measuring device as well as it can generate waveforms in terms of amplitude and time because it is very easy to measure the amplitude of the voltage signal to determine its intensity. The non-electrical … [Read more...] about Cathode Ray Oscilloscope
Difference between RC and RL Circuit
The major difference between RC and RL circuits is that the RC circuit stores energy in the form of the electric field while the RL circuit stores energy in the form of magnetic field. The RC circuit is formed by connecting a resistance in series with the capacitor and a battery source is provided to charge the capacitor. The RL Circuit is formed by connecting a resistance with an inductor and a battery source is provided to supply the current to the inductor. Another significant … [Read more...] about Difference between RC and RL Circuit
Light Activated SCR
Definition: LASCR or light activated SCR is a semiconductor device which turns ON when it is exposed to light. The constituent element of SCR is silicon, and it works like a rectifier, and thus, it is termed as Silicon Controlled Rectifier. The LASCR is a type of thyristor which is triggered by photons present in the light rays. It is a three terminal device, consists of cathode, anode and gate terminal. The gate terminal is used when the electrical triggering is supplied to the LASCR. The … [Read more...] about Light Activated SCR
Transducer
Definition: Transducer is a device that holds the ability to change a form of energy into another. Transducers are of various types such as electrical transducers, mechanical transducer, thermal, optical, acoustic etc. An electrical transducer is the cornerstone of electronics instrumentation because it converts the physical quantities which are non-electrical in nature into electrical quantities. This is because in instrumentation we need to measure the quantities and electrical quantities … [Read more...] about Transducer
Difference between DC Voltmeter and AC Voltmeter
The major difference between DC voltmeter and AC voltmeter is that the DC voltmeter measures the peak value of DC voltage while AC voltmeter measures the RMS value of AC voltage. Another significant factor which differentiates DC voltmeter and AC voltmeter is their working principle. The DC voltmeter selects a particular voltage and attenuates the rest of the range of voltage and then amplifies the selected voltage and passes it to PMMC meter. AC voltmeter uses a rectifier before amplifying … [Read more...] about Difference between DC Voltmeter and AC Voltmeter
Difference between LED and LCD
The main difference LED and LCD is that the LED works on the principle of electroluminescence i.e. it generates light due to recombination of electron and holes while LCD do not generate light of its own but control the light energy and modify it in such a way that some area of the display screen appears bright while some areas appear dark. Although, LED and LCD both are the types of the display device but the brightness level of LED is more than that of LCD. The power requirement is also one … [Read more...] about Difference between LED and LCD
Difference between Online UPS and Offline UPS
Online UPS and Offline UPS are the two crucial types of UPS. Both supply power to the device in case of power outage. But the similarities end here. The main difference between Online UPS and Offline UPS is that the Online UPS provides the power with the help of rectifier and inverter combination. It simultaneously provides power to load as well as the battery so that battery can be charged to supply power in case of power failure. On the contrary, an Offline UPS supplies AC power directly to … [Read more...] about Difference between Online UPS and Offline UPS
Uninterruptible Power Supply
Definition: UPS is an acronym of Uninterruptible Power Supply, it is an electronic device which is used to supply power to other devices such as a computer, telecommunication equipment etc. in case of power outage. The rectifier present in the UPS converts the AC power into DC, then the battery stores the DC power. This process continues when the AC power is on. When there is the power outage, the inverter converts the DC power into AC which is required for the functioning of the … [Read more...] about Uninterruptible Power Supply
