The resistors R1 to R5 in the provided circuit diagram are connected in parallel. Here’s the reasoning:
Node Identification
- The circuit has two main electrical nodes:
- The top node, where all the resistors (R1, R2, R3, R4, R5) are connected together.
- The bottom node, which is the common return path (ground/reference) for all the resistors.
Why Parallel?
-
In a parallel configuration, all components share the same two nodes. This means:
- The voltage across each resistor is the same (10 V in this case).
- The total current IT splits among the resistors, and each resistor can have a different current depending on its resistance.
-
Visually, you can see that one terminal of each resistor is connected to the top node, and the other terminal of each resistor is connected to the bottom node. This is the defining characteristic of a parallel connection.
Contrast with Series
- In a series configuration, components are connected end-to-end, so the same current flows through all resistors, and the voltage divides across them. This is not the case here.
Conclusion
The resistors R1 to R5 are in parallel because they all share the same two nodes.
