ITIKAA LED AC/DC BULB

                  AC/DC BULB / EMERGENCY BULB

It will act like a normal light bulb, with power on When there is a power outage, it will act as an emergency light.

Let's start by making it clear to everyone, both voltages are for different applications and have their own utility, so they should not be compared as they serve different purposes.The terms AC and DC (Alternating Current and Direct Current), are terms that all they have learned in high school science classes. But when it comes to light bulbs, what is the difference between lighting and AC and DC bulbs? To better understand this, we can go ahead and get an overview of what exactly AC and DC are.

The magnitude and direction of an alternating current change while that of a direct current remains in the same direction. Alternating current is the way businesses and residences

they receive their electricity supply. In the alternating current type, the current in the circuit comes and goes constantly. Alternating current is supplied by a power plant. All residences usually have alternating current supplied by a substation that is fed by the power plant. The direction of the alternating current changes 50 to 60 times per second. This is known as hertz (hz). Hertz is the reason a light bulb seems to be constantly on, even though the current changes so many times.

AC voltage also allows us to use a magical device called a transformer, the transformer allows us to take voltage and current on one line, then generate a different voltage and current with the same total power (watts) on another line. We cannot do this efficiently with DC power. Therefore, AC power is used because its voltage can be increased to super high levels and the current reduced to a trickle. Making it ideal for long distance transmission.

Using alternating current saves energy because it uses higher voltages to send smaller currents, which also significantly reduces heating in the wires, which is known as resistance. Transformers can convert a high voltage current to a low voltage current and vice versa. Alternating current travels even faster when it is high voltage, so transformers increase the voltage when the current is sent and other transformers decrease the voltage before it is redirected to homes and businesses. Direct current can also be used in lighting and light bulbs, but it takes a lot of energy and effort to send it to far distances. Let's put it this way, low voltage direct current cannot travel very far without losing its power. The further you have to travel, the thicker the wiring will be. Which can be very expensive.

DC - Direct current, on the other hand, comes from battery sources, rectifier bridges, solar panels, cars, boats, etc. The current is passed through conductors, as well as semiconductors and insulators. Cables are an example of conductors. DC wiring is usually red and black, with red being positive and black being negative.

All electricity distribution in the world uses alternating current for its multiple advantages in terms of transmission and use of transformers. If direct current is required, then the alternating current that is distributed to a substation becomes direct current.

In a light bulb, the filament in the light bulb acts as a resistor to electrons that otherwise flow unimpeded through the wire. Although the electrons can still pass through the filament, just like they pass through the wire, this requires more effort on your part. It is this work that electrons have to do to overcome the resistance caused by the filament that generates the heat that makes the filament ignite.
