One of the questions that hobbyists ask over and over is how to select the value of a current limiting resistor for an LED. Usually the seat of the pants response is: “Subtract 2 V from the supply ...

144 LEDs total. Three sets of 48 in series connected in parallel. My problem is I don't know what value to use for R1. I'm thinking 600 ohm, but I really don't know how to calculate this. I'm making ...

The circuit is designed for power supply protection by limiting the amount of maximum output current to prevent any further damage to take place inside the power supply as well as the external circuit ...

This paper dial makes selecting current limiting resistors a snap. [Giorgos Lazaridis] came up with the tool, which he describes in detail in the Worklog tab of his writeup. If you want one of your ...

If you got your start in electronics sometime after 1980 your first project might well have been to light up an LED. Microcontroller projects often light up an LED, too, and a blinking LED is ...

VCC has designed a series of LED sockets that feature a built-in current limiting resistor to provide optimal LED performance. VCC has designed a series of LED sockets that feature a built-in current ...

Adding a clamp circuit to the well known current-limiter protects the "pass" transistor from over-currents when load faults occur. Most readers are probably familiar with two-terminal current-limiting ...

• The inductance in a stepper-motor phase winding limits how fast current rises when power is applied. • Series-resistor current limiting needs higher voltages for faster step rates, but higher ...
