He is currently a contributor to boing boing wink books and wink fun. The ballast resistor is used to limit the current through the led and to prevent that it burns. What Is The Function Of A Resistor Functions Explained With Which Resistor Should I Use With My Led Kitronik Calculating Current Limiting Resistor Values For Led Proper parallel led circuits have a series resistor for each led. Why use resistor in led . He is the author or editor of over a dozen books on technology diy and geek culture. To limit the current in the led to a safe value. If you would attach an led to a 5 volt power supply directly you would burn it instantly. So its vital to stay within the limits of the led. The simplest circuit to power an led is a voltage source with a resistor and an led in series. Leds are semiconductors diodes in particular. When...

Heres an analogy i like that illustrates why we need end of line terminations. I have also heard that the actual frequency is not the matter but that the matter is the speed at which the actual signal changes from high to low and vice versa. Solved Ddr Ii Termination Resistor Community Forums Why Isn T An End Of Line Resistor Used The Same Way As A Proper Can Bus Termination Electrical Engineering Stack This is intended to prevent signals from reflecting off the end of the transmission line. Why termination resistor is needed . Have a can node that may need to be removed occasionally and it will. Here length is determined in terms of wavelengths. The two caveats of this type of termination are that it requires one extra component on each termination network and the series resistor and capacitor introduce a resistor capacitor rc delay. Most of ...
