current and voltage sources

ashu

may be it's basic and foolish to asking this question. but i m still confuse different b/w current and voltage sources. we used to say ac 230 volt (in India 50 hz) comes in our home is current source ...or not

i m confuse then what is AC current and voltage source and what is DC current and voltage source

pl explain with examples.
 
Hi ashu,

See there cannot be any current flow without voltage. you just imagine how can be the current flow exist without potential difference.

In our country, we are using 230V ac supply for residential purposes, but current flow will vary based on load what we are using...

Ex: If suppose you are using following applications in your home :

1. Computer - 100Watts
2. 100 Watt bulbs - 3nos - 300watts
3. 2 ceiling fan - 2*100 - 200watts

Then total power consumption is 600Watts

So total current flow is 600/230= 2.60Amps

Finally, its clear that voltage remains the same but current varies based on load
