Two resistors of resistances `R_1 = 100 pm 3` ohm and `R_2 = 200 pm 4 ` ohm are connected (a) in series , (b) in parrallel. Find the equivalent resistance of the (a) series combination , (b) parallel combination . Use for (a) the relation `R = R_1 + R_2 and ` for (b) `1/R = 1/(R_1) + 1/(R_2) and (DeltaR')/(R^(,2)) = (DeltaR_1)/(R_1^2) + (DeltaR_2)/(R_2^2)`

Explanation

To solve the problem of finding the equivalent resistance of two resistors \( R_1 = 100 \pm 3 \) ohm and \( R_2 = 200 \pm 4 \) ohm connected in series and parallel, we will follow these steps:

### Step 1: Calculate the Equivalent Resistance in Series

The formula for the equivalent resistance \( R \) in series is given by:

\[
R = R_1 + R_2
