Direction of AC current through AC mains

[Kartik.]

What would be the direction of the current from the mains till it completes its one full path and the appliance used in the circuit starts working?

That would change 50 times per second.

in how many seconds does the current flows throughout the complete loop once and does it change directions within that period ?

Kartik, mrspeedybob gave you the correct answer: the current in the loop changes direction fifty times during each one second.

I think you are confusing electron flow with current flow. This may help - http://amasci.com/miscon/speed.html

so, current starts flowing right away.. and how many times it changes direction depends on the frequency. 50Hz would give you the answer where the current will change direction 50 times in a second. In the US however, it is going to be 60Hz. this applet may help you visualize it better - http://www.falstad.com/circuit/#$+1...w+448+272+448+304+0 o+1+64+0+35+5.0+0.1+0+-1
