Why Is A Resistor Used With An Led

Lets do one more example this time with a white led you can find some here and a 3xaa battery box such as this one. An led usually has a resistor connected in series with it because an led light emitting diode is not linear in current to voltage like a resistor and has to be operated within specified. Morimoto Led Load Resistor Automotive Led Accessories From Choosing The Resistor To Use With Leds 3 Steps Instructables Ldr Circuit Diagram Build Electronic Circuits Apply a bit more voltage and there is current and the led lights up. Why is a resistor used with an led . In parallel circuits the total circuit current is divided among all of the branch. The ballast resistor is used to limit the current through the led and to prevent that it burns. Proper parallel led circuits have a series resistor for each led. Reply 2 years ago reply upvote. Obv
