Question

Are the two resistors in FIGURE Q28.7 in series or in parallel? Explain.

Short answer

Both resistors are connected in series.

Step-by-step solution

Given information and formula used 

Given Figure:

Theory used :

In a series circuit, all components are connected end-to-end, forming a single path for current flow.

In a parallel circuit, all components are connected across each other, forming exactly two sets of electrically common points.

Determining if the two resistors in the given figure are in series or in parallel 

When the resistors are linked one by one, without any connections in between, they're referred to as being related in a series.

The two resistors in the given figure are linked from each end and one by one, as illustrated in the diagram.

As a result, both resistors are connected in series.
