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 types of electricity are used in Australia?
240V AC 50HZ

What are the key differences between alternating current (AC) and direct current (DC)?
Alternating current (AC) and direct current (DC) differ in the direction of flow of electric charge. AC changes direction periodically, while DC flows in one direction continuously. AC is used for long-distance power transmission, while DC is used for electronic devices and batteries.
What voltage is used in Ireland?
The voltage used in Ireland is 220V AC, at 50Hz.
What is a type of electricity that continuously changes direction?
Alternating current (AC) is a type of electricity that continuously changes direction, typically used in homes and businesses for powering appliances and devices. This differs from direct current (DC), which flows in one direction only.
What is the meaning of 230V ac and 50Hz ac supply?
It is an AC supply with an rms voltage of 230 v and a frequency of 50 Hz, as used throughout Europe.
