Hi friends,
I am a physics student. But I am very much intersted in Economics. But I really don't know how the value of currency changes everyday? One more thing: Everyday I read in newspapers that Sensex incresed by a particular value or something similar. SO what actually is sensex and how it varies?

Can you help me?

If want a long explanation:

Briefly, the exchange is, in part, determined by the demande of the currency from foreign investor and the supply. The demand is partly drived by interest rate. For example, the interest rate in Canada has been higher for the last two years. This brings US investors (those interested bonds and other similar investment) in Canada and therefore increase the demand for Canadian money and increasing the supply of US money. So the end results is a rise of the Canadian dollar from 0.60 US $to 0.80 US$.

Sounds like the dow jones which doesnt have a whole lot to do with currency. Isnt the main currency exchange in the US the NY mercantile exchange?

NY Mercantile Exchange also deals in futures, things other then money. Perhaps in India its a all in one deal?
