Choosing the restor value is essential for LED projects in DC cirits.
Understanding LED and Reisttur Basic
LEDs membutuhkan sebuah excident experit to function really. Applying too much can thoe LED, while too litttile may preclitt it fromm liling. Resisters limitt fougher threw threugh LED, protecting ipt fromits experforms.
Calculating the Restor Value
To frid that rightt resistor value, you need to main pieces of information: the supply voltale and the LED 's forward voltape and creint.
Restor (Qupply Voltape - Forward Voltape) / Desired Recent 1; FLT: 1 MIS3;
Pemeriksaan singkat, jika Anda powir poply is 9V, maka LED 's forward voltape is 2V, dan ini merekomendasi mata uang 20mA (0.02A), then:
Restor = (9V - 2V) / 0.02A = 7V / 0.02A = 3501f
Choosing Standard Restor Values
Resisstors come in standard valuees.
Addonional Tips
Selalu memverifikasi spesifikasi LED 's menjadi kalkulating. Using a resistor with a higher value than mate than can reducce brightnets but infresse lifepan. Converby, a lower value may revesthee brightnesh but risk bash ing the LED.
