Alternating current

Shantanu Agrawal:
1
Alternating current means a current that changes magnitude with time.
2
Alternating current is supplied in home.
3
 Magnitude of Alternating current changes but Why SPEED OF FAN DOES NOT CHANGE WITH TIME ?
4
Magnitude of Alternating current changes but Why  glow or intensity of light does not change with time ?

[16:53, 6/17/2018] Saurabh Kumar: I think  polarity changes that depends on frequency. 
Magnitude remains constant in both directions.

[16:38, 6/17/2018] Akshay Indore: In fans
[16:38, 6/17/2018] Akshay Indore: There is capacitor
[16:38, 6/17/2018] Shantanu Agrawal: OK
[16:38, 6/17/2018] Akshay Indore: Which use to store, high current or voltage,then nrml
[16:38, 6/17/2018] Akshay Indore: And when voltage or current is low
[16:39, 6/17/2018] Akshay Indore: Then store enegery in capacitor

[16:39, 6/17/2018] Akshay Indore: Use to trnsfer required current n voltage to fan
[16:39, 6/17/2018] Shantanu Agrawal: OK
[16:39, 6/17/2018] Akshay Indore: Therefore fan speed doesn't chnge
[16:40, 6/17/2018] Akshay Indore: Similar in case with light,instead of capacitor,light ( tube light ) having starter
[16:40, 6/17/2018] Akshay Indore: Functioning is same
[16:40, 6/17/2018] Akshay Indore: My question is

Why same fan n tube light run faster n brighter ,when it run on invertor
[17:45, 6/17/2018] Akshay Indore: Question for u bro. 
[19:45, 6/17/2018] Shantanu Agrawal: No idea
[20:13, 6/17/2018] Akshay Indore: Think about it

[21:49, 6/17/2018] Shantanu Agrawal:   OK
ठीक है
