user37853: I want to use a load cell (Capable of measuring up to 1 ton) connected to a arduino board.
I am a beginner, my questions are as follows :
1. How to calculate the current generated by the load cell ?
2. If current is too high, how will We make the arduino use the current to display weight ?
p.s If you know some helpful articles that might help me learn, please suggest.

user47766: You need to use a load cell amplifier between the Arduino and the load cell. Load cells are around 350 Ohms. Four wire. And the signal that needs to be measured are very small. 
The current will not be too high. The question indicates that you don't understand the application. (and therefore you are looking for help)
Here are some useful links.

A typical load cell has an output of 2 millivolts per volt of excitation voltage at the full rated weight. For example, if 5 volts were used for the excitation voltage, and the output is 2 mV/volt, then the voltage out would be 10mV at full scale. The voltage difference (compared to the unloaded load cell) is what is measure.
If the excitation voltage (just a technical name for applied voltage) were 5 volts, the voltage at the output terminals, measured from the negative terminal, would be 2.5 volts, half of the applied voltage. But this 2.5 volts is not the measured output. What is measured is the difference between the +signal and the -signal wires.    

user57029: My suggestion would be to make a spreadsheet with some items of known weights. Generally while using scales you’ll have a 5lb calibration weight that has a very tight tolerance. You can find the output voltage changes and map it from 0-1023. 
This should mean for every 2.2lbs you will get another increment. Not extremely accurate but fine when measuring at the ton scale
