I have 4 resistors R1=R2=R3=R4=40[tex]\Omega[/tex]
I need to find the Equivalent Resistance when they are connected in series and when they are connected in parallel.
The problem is my answer for the parallel differs from the answer given in the book.
The Attempt at a Solution
The first is easy: 4*40=160
in the book the answer is: 10[tex]\Omega[/tex]
