Problem 2.5 Source: Problem elaborated by the author of the site.
Calculate the equivalent resistance Req, between the a-b points of the circuit shown in Figure 02-05.1.
Solution of the Problem 2.5
Note that the resistors R1 and R2 are in parallel. Therefore, we must solve the parallel with the equation shown below.
By substituting for numeric values, we have:
So R12 is in series with R3. So to calculate the equivalent resistance of the circuit just add the values, or:
