LEDs are semiconductors, diodes in particular. The current flowing in an LED is an exponential function of voltage across the LED. The important part about that for you is that a small change in voltage can produce a huge change in current. That is the most important concept of this article. Resistors aren't like that. The current and voltage in a resistor are linearly related. That means that a change in voltage will produce a proportional change in current. Current versus voltage is a straight line for a resistor, but not at all for an LED.
Because of this, you can't say that LEDs have "resistance." Resistance is defined as the constant ratio of voltage to current in a resistive circuit element. Even worse, there's no real way to know exactly the relationship between current and voltage for any given LED across all possible voltages other than direct measurement. The exact relationship varies among different colors, different sizes, and even different batches from the same manufacturer.

Why bulb is resistive load?
the filament is made of tunguston which is having high resistance value,Hence it's resistive load
Can you use a dimmer switch with A19 incandescent bulbs?
Be it a tungsten or LED A19 bulb, both are usable with a dimmer switch. However LED bulbs require special dimmers to work correctly. Normal dimmers, those used for regular tungsten (incandescent) bulbs, use the resistive load of the bulb to allow dimming. Most LED bulbs require other methods to dim the bulb. One stop gap fix to use a regular dimmer is to add a small wattage bulb to the LED bulb circuit. That adds a resistive load to fool the older dimmer. The best option for dimmable LEDs is to ensure you have a dimmer that specifically states it works with dimmable LEDs.
Why LED uses less electrical energy?
LED uses less electricity because LEDs convert electrical energy into light more efficiently than standard light bulbs. The resistive wire in a standard light bulb wastes the energy supply as heat whereas an LED light does not.
Is a cf bulb a resistive load?
No, CFL bulbs have a power factor of 0.6-0.7.
Which bulb is brighter, the incandescent or the LED?
The LED bulb is brighter than the incandescent bulb.
What is the full form of LED BULB?
An LED bulb simply means a Light Emitting Diode Bulb—a bulb that uses LED technology to produce light efficiently.
What is the equivalent brightness of a 9W LED bulb compared to traditional incandescent bulbs?
A 9W LED bulb is roughly equivalent in brightness to a 60W incandescent bulb.
What are the benefits of replacing a refrigerator bulb with an LED bulb?
Replacing a refrigerator bulb with an LED bulb can save energy, last longer, and provide brighter light.
Why is my LED bulb flickering?
Your LED bulb may be flickering due to a loose connection, incompatible dimmer switch, or a faulty bulb.
What is the equivalent of a 6W LED bulb in terms of traditional incandescent bulb wattage?
A 6W LED bulb is equivalent to a 40W traditional incandescent bulb in terms of brightness.
What is the equivalent brightness of a 6W LED bulb compared to a traditional incandescent bulb?
A 6W LED bulb is equivalent in brightness to a traditional incandescent bulb of about 40-60 watts.
How can I repair a LED light bulb?
Repairing a LED light bulb is not recommended as they are designed to be replaced rather than repaired. If the LED light bulb is not working, it is best to replace it with a new one.
