Introduction This post provides instructions on how to move from 7-11’s mobile phone service called Speakout to Freedom Mobile and retain your phone number. ⚙ These step-by-step instructions will work …
This tool calculates the current through a Light Emitting Diode (LED). To calculate the current draw through an LED, you need to know the voltage supply (V), the forward voltage …
This calculator can help you determine the appropriate resistor value for a LED forward voltage drop and power supply. The resistor is used to limit the amount of current into …
In the context of Ethernet cables, “MHz” refers to megahertz, a unit of frequency that measures the bandwidth capacity of the cable. The picture below shows a cable rated for …
This calculator finds the series resistor value to be used with an LED and a +12 Volt supply. This resistor limits current into the diode and is required for proper …
