Dania:
Each experiment has different errors & uncertainties for example in electricity questions while measuring resistance, we do not consider lead contact resistance, so that's an error too :)

You're indeed right :)
We can also talk about the uncertainty in the measuring instruments used such as voltmeter or ammeter. ;)

Wat is lead contact resistance?

Ooh.......it is the contacts that you use to join the different electrical components together. They are usually found at the end of each connecting wires.
It's something like that though am pretty sure you'll be getting one much older and uglier than this one for your practicals :P

haha ok yeah i know what u mean now :)
