Voltage drop across resistor calculator

J b weld instructions LED Resistor Calculator Single led - Leds in series - Leds in parallel Voltage drop is usually 1921V for AlGaInP 3135 for InGaN and 12V for Infrared. That means we can calculate the voltage drop or simply the voltage across each resistor as we have the resitance value as well as the current value.
