10.2 Combining resistors

Question 1

When resistors are connected in series, how is total resistance calculated?

Answer 1

R(total)= R(1)+ R(2)+ …+ R(total number of resistors)

Question 2

When resistors are connected in parallel, how is total resistance calculated?

Answer 2

1/R(total)= 1/R(1)+ 1/R(2)+ …+ 1/R(total number of resistors)
