In an experiment, the voltage across a resistor is V= (74.1 ± 0.4) V and the current through it is l=(0.9 ± 0.1) A. What is the error on the resistance R (in Ω)? (Report your value with 1 decimal digit).

Homework Answers

Answer #1

Given that:

V = (74.1 ± 0.4) V

I = (0.9 ± 0.1) A

Resistance is given by:

Now error in Resistance is given by:

Rounding into 1 decimal digit:

  • That is, Error in resistance will be ± 9.6 Ω
