Question

A student verifying ohms law computed the value of resistance of a resistor for each set of observation.however the value of resistance were slightly different from the actual value . Is his experiment wrong?Justify your answer.

Answer 1

No! The experiment is not wrong. Resistance depends on various factors such as heat, area and length of the wire. All of these quantities can have some amount of error while measurements. So, a little deviation from the original value does not mean its wrong.

Answer 2

Answer is, NO

Since the resistance of a resistor depend on factor like heat, current, work done.
