SCIENCE AND TECHNOLOGY

How fans work.
All fans work by moving the air that is in the area of the fan this movement of air creates a breeze which is felt on the skin of the person that is in front of the fan. While this breeze itself does not actually feel cool there is a cooling effects from the fans air the air allows your skin to evaporate sweat faster cooling your skin

How electric fans work?
Electric fans are comprised of a motor run by electric current which is attached to fan blades via a shaft. This rotor shaft is run by the motor and turns the fan blades and the general revolution per minute of the motor can vary greatly depending on the model of the electric fan

PARTS OF AN ELECTRIC FAN

• Blades
• Hub
• Motor
• Guard
• Mount
• Switch
• Wiring
• Cord

FACTS ON ELECTRIC FANS

• The hub is the one who spin the blade so the switch control its speed
• When the fans wind is cold it means that it in a cold place and when the fans wind is how it means it's in a hot place
• When the fans mode become higher it will need more volts to power
• It will depend on the quality of the fan on how strong its wind will be

Type of electricity to work a single fan
Altering current(ac) and direct current (dc)batteries use direct current,where the electrical current houses use altering current ,where the electrical current changes direction too on several times a second.

Air conditioning
Widespread use of air conditioning units has greatly reduced the prevalence of electric fans, unlike fans, air conditioners actually decrease the temperature of the air by using refrigerants air conditioners use much more electricity than fans.using fans the breeze of outdoor will be blown away by the fan and the fan will not do much work so it conserve energy

Wattage and power draw
Like any other electrical device fan use a combination of voltage and amperage to operate .
