I did a lab on DC circuits, and we calculated the resistance of multiple resistors in parallel.
Resistance of Resistor 1 & 2 = 1000 +/- 5%
so R1 =1000+/- 50
R2= 1000 +/1 50
i need to calculate R using the equation...
R= 1/R1 + 1/R2
I am confused as to what the uncertainty would be for R...please help!!
This is a classic trick question.
Read the section on parallel resistors:
