Do Leds Have A High Resistance. From the calculator above, when the supply is +5 v, the minimum series resistance is 100 ohm. An led can be approximated as a resistor with a fixed voltage source.

If we look at a typical led iv curve we can see that it is approximately linear. A higher resistance restricts current flow, resulting in a dimmer led, while a lower resistance allows more current, leading to a. A series resistor will ensure that slight differences in voltage have only a minor effect on the led's current, provided that the voltage drop across the resistor is large enough.

Every led has a specification for the maximum amount of forward current it can withstand without damage. From the calculator above, when the supply is +5 v, the minimum series resistance is 100 ohm. Both leds and resistors have tolerances, but usually cheap resistors have larger tolerances than leds. An led can be approximated as a resistor with a fixed voltage source.
