q: what is calibration ?
i dunno how to ans this question

I guess when we add markings to some measuring thing between 2 know fixed point,like in calibration of thermometer.

Just draw a circuit with an ammeter and rheostat.

I know that! but where should I complete the circuit like around one end to the other?

Keep in mind to have battery connections correct.so current can flow in right direction.

Thank you so much! And when we have to draw the switch we can place it anywhere in the circuit right?
And, the cooling curve for water cooling down in shiny , black container would be like the black and white would decrease from the top of graph to the bottom(curved) ... but the black would decrease rapidly first and meet the shiny after a while right?

Wouldnt the battery be on the opposite side of ammeter???

It doesnt matter.It just has to be in series.
