In an experiment, values of two resistances are measured to be r=(5.0+-0.2)ohm and R=(10+-0.1)ohm.Find the values of total resistance in (i)series (ii)parallel?

Expert Answer:

If in series;
 
Just add both the resistances:
 
 
Reff = r+R= 5.2+10.1
 
If in parallel
 
1/Reff = 1/r + 1/R = 1/5.2 + 1/10.1
