I is the symbol for current. R is the symbol for resistance. It is the only formula in electronics that I use pretty much every time I design a circuit. You can switch it around and get R = V/I or I = V/R. As long as you have two of the variables, you can calculate the la...
A light-emitting diode (LED) is a semiconductor device that emits light when an electric current flows through it. Based on the semiconductor material used and the amount of doping, an LED will emit a coloured light at a particular spectral wavelength wh
Q1: What is the purpose of PCB symbols? A1: PCB symbols allow engineers to represent components and connections in schematics and layouts visually for simplified design, simulation, production and servicing of electronics hardware. They convey the circuit information efficiently through standardized graphi...
Google has possibly created the first quantum computer that can perform fast theoretical problem solving, but competitor IBM is disputing the claim.
It is used to send HD signals over a single cable. HDMI can be used for transmitting both audio and video over a cable. What does an HDMI adapter do? The adapter gives you an HDMI connection if your TV does not come with an HDMI port. However, almost all modern LED TVs come with ...
Understandtheir importance in the signal chain Are you ready to get started? Let's go! Introduction Analog signalsneed to be correctly"prepared"before they can be converted into digital form for further processing.Signal conditioningis an electronic circuit that manipulates a signal in a way that ...
Varistors- the resistance is a function of voltage Magneto resistors- the resistance is a function of magnetic field Strain gauges - the resistance is a function of mechanical load For each of these types, astandard symbolexists. Another breakdown based on the material and manufacturing process can...
Some optoisolators can also transfer analog signals by changing the light source’s intensity. How Optoisolators Work The basic working principle of an optoisolator is shown in the figure below. The input circuit consists of a variable voltage source and an LED. The output circuit consists of...
Impedance matching typically involves matching the impedance of a power source to the impedance of an electrical load. Maximum power is transferred from the source to the load when the impedance of the load is matched to the impedance of the source, improving the efficiency of the circuit. If ...
OCR systems use a combination of hardware and software to convert physical, printed documents into machine-readable text. Hardware, such as an optical scanner or specialized circuit board, copies or reads text, then software typically handles the advanced processing. ...
