In the case of an incandescent lamp, the variation in current due to its frequency maintains its temperature, so its light output is continuous. For lamps such as fluorescent tubes, the resulting flicker is not noticeable due to a human's persistence of vision -i.e. the same characteristic that allows us to watch film (a series of still images above around 16 frames per second).

Are Christmas lights ac or dc current?
Christmas light have always been AC.
In India the alternating current ac change its direction time within one second?
I believe India runs on 50Hz power, so 100 times.
Ac vs DC current?
DC (direct current) means the current flows only in one direction. In AC (alternating current), the current changes direction continuously (for example, 50 or 60 cycles per second).
How can you differentiate DC and ac?
DC is direct current. It is characterized as a voltage or current that is constant or, more precisely, always in one direction. A battery is an example of a DC source. AC is alternating current. It is characterized as a voltage or current that is alternating, i.e. changing direction at some frequency such as 50Hz or 60Hz. The power supplied to your home from the public power utility is an example of an AC source. ac is attractive in nature while dc is repulsive .
How many hertz in direct current?
Direct current has no frequency, it has voltage. also it has current that is measured in Amperes which is dependable of the resistance of the circuit. Alternating current has frequency because the electricity flows alternatively on both directions. If the frequency of AC is 50hz/s it means that the electricity flows forwards and backwards 50 times per second.
What does AC mean about current flow?
AC means Alternating Current. Alternating Current changes direction constantly, usually at 60Hz (US, Canada, and others) or 50Hz (UK and others).
What is AC current?
An AC current (alternating current) is one that changes its direction continuously - typically at 50 or 60 Hertz (cycles per second).
What is the frequency of ac in Egypt?
220v 50Hz
Are Christmas lights ac or dc current?
Christmas light have always been AC.
In India the alternating current ac change its direction time within one second?
I believe India runs on 50Hz power, so 100 times.
What is ac energy?
That probably refers to an AC current or an AC voltage. That means that the electrical current is not continuously flowing in one direction, but changes direction all the time - typically at a frequency of 50 or 60 cycles per second in the case of household current. Similar for the voltage.
Ac vs DC current?
DC (direct current) means the current flows only in one direction. In AC (alternating current), the current changes direction continuously (for example, 50 or 60 cycles per second).
What types of electricity are used in Australia?
240V AC 50HZ

What is an electric current that periodically changes direction?
There are two types of electric current, DC or direct current and AC or alternating current. The power delivery to homes in most places in the world is AC or alternating current. This is where the electrons are pushed one way then back the other way with usually 100 or 120 changes in direction per second. This produces 50 or 60 forward/back cycles every second called 50Hz or 60Hz.
What did telsa discover or invent?
Light bulb (ac current)
What voltage is used in Ireland?
The voltage used in Ireland is 220V AC, at 50Hz.
