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.

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.
What is the load of a flashlight circuit?
The load of a flashlight circuit is the component that consumes electrical power, typically an LED bulb or an incandescent bulb. The load transforms electrical energy into light energy to illuminate the flashlight. It is an essential part of the circuit that determines the brightness and performance of the flashlight.
Maximum load 1800W resistive - 600W tungsten?
The maximum load for resistive devices is 1800W, while for tungsten devices it is 600W. This means that devices with resistive load can safely draw up to 1800W of power, while devices with a tungsten load should not exceed 600W to prevent damage to the equipment and ensure safety.
What does 12 amps resistive load mean?
A resistive load just describes something like a toaster, electric water heater or space heater, where the load is relatively constant. The description is used to distinguish from something like an electric motor, which uses much more current at startup then drops off significantly after it is running.AnswerIn a.c. circuits, a resistive load describes a load whose load current is in phase with its supply voltage. Expressed another way, it is a load having unity power factor. Resistive loads are not necessarily constant -for example a tungsten-filament lamp has a low resistance when cold and a high resistance at its operating temperature.
Does 1000va equal 10 amps?
No, 1000VA does not necessarily equal 10 amps. The relationship between VA (volt-amperes) and amps depends on the power factor of the load. For a purely resistive load (like an incandescent light bulb), 1000VA at 120V would be equivalent to approximately 8.3 amps.
Why bulb is resistive load?
the filament is made of tunguston which is having high resistance value,Hence it's resistive load
Is a cf bulb a resistive load?
No, CFL bulbs have a power factor of 0.6-0.7.
Is computer is Resistive load?
It is resistive much load
Do air conditioners use resistive load or inductive load?
resistive loadAnswerIf the current is driving a motor, then the load is resistive-inductive.

In a circuit with resistive and inductive load what happens to the power factor as the resistive load increases?
The PF will increase
Is a geyser a inductive load?
No, a geyser is a resistive load.
What are the specifications of resistance?
specification of inductive load,capactive load,resistive load in laboratory
What is the least destructive load to switch?
No load is the least destructive load to a switch.

Fax machine that operates on 120V and it say max wattage is 170W Can you connect two machines in series or one bulb of 170W in series with this machine to 220V outlet?
Connecting a machine in series with a bulb to try to use it on a higher voltage is inadvisable. The machine will have, at least in part, an inductive load, which will not equate to the purely resistive load of a bulb.
What is an example of resistive load?
Some examples of resistive loads are: heaters, incandescent lights, fans etc.
