Question

do the experimental and theoretical values of voltages and current agree?give reason for ant discrepancies

Answer 1

No, Experimental and theoritical values of current and volatge donot agree with each other because the the experiment is use to be based on the basis of ideal cases and ideal instruments with zero internal reistances and perfect environment with ideal perfect equipement without even a marginal error but in reality most of the equipements are measured by human beings while making experiment so error and discrpancies are natural most instruments have heating effect internally and some time environmental heating and other factors too affect the experiment and hence the values .Intenal resistances heating effect at the leads of the wire all these affect the experiment and instrumental factors some times manufacturing deffect in measuring instruments even the amount of current may be low to be measured.Residual magnetism also affects the expermental values hence they donot match and agree.
