Nettet20. apr. 2016 · 5. Although it makes no difference from the perspective of the parts, there is a practical reason- in an environment such as a motor vehicle the negative side of the DC power is traditionally connected to the chassis. If you put a resistor (say for an LED) on the positive cable then a short of the wire to the chassis will draw limited current ... NettetStep 3: Connecting the LEDs. For each LED, connect the negative side (shorter leg) of the LED into the same row of a resistor. Not on the same row as the negative column but on the same row as the other leg of the resistor. Then connect the positive side (longer leg) of the LED into other holes in a different column and row on the breadboard. uk hundred pound note

Why does a resistor need to be on the anode of an LED?

Nettet18. okt. 2012 · Then a high output won't light the LED because the output FET is switched off. A low output will draw the 20 mA through LED, resistor and open-drain output. Note that this will invert the logic: in your first schematic the LED will be off when the output is active, in the second circuit it will be on with active output. edit NettetFor an LED to work it needs to be connected to a voltage source with the correct side. The voltage supply side of the diode is the positive (+) side, this is called the anode. The …
