The voltage drop across a lit LED is approximately constant over a wide range of operating current; therefore, a small increase in applied voltage greatly increases the current. Datasheets may specify this drop as a "forward voltage" at a particular operating current. Very simple circuits are used for low-power indicator LEDs. More complex ...
Simple LED circuit with resistor for current limiting. The current in an LED or other diodes rises exponentially with the applied voltage (see Shockley diode equation), so a small change in voltage can cause a large change in current. Current through the LED must be regulated by an external circuit such as a constant current source to prevent ...
Architectural wiring diagrams show the approximate locations and interconnections of receptacles, lighting, and permanent electrical services in a building. Interconnecting wire routes may be shown approximately, where particular receptacles or fixtures must be on a common circuit.
A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.
A circuit diagram representing an analog circuit, in this case a simple amplifier. Analog electronic circuits are those in which current or voltage may vary continuously with time to correspond to the information being represented. A simple schematic showing wires, a resistor, and a battery. The basic components of analog circuits are wires ...
If you've lost weight recently, and your hair has gone with it, there's a simple explanation, say experts. Here's what you can do to regrow hair after weight loss.
Circuit designers, who are compensated for their expertise in creating electrical circuits, bear the responsibility of ensuring the safety of consumers who purchase and use these circuits at home. The risks associated with neglecting the prototyping process and releasing a flawed electrical circuit are significant.
A Florida grandfather preparing to celebrate Thanksgiving with his family and friends was shot to death by his neighbor inside a gated community as the two argued over loud music. Hureleyon McLean ...
