Final answer:
To identify the series and parallel sections of a combination circuit, examine the circuit diagram and determine if the resistors are connected in series or parallel.
Step-by-step explanation:
If the same current must pass sequentially through the resistors, they are connected in series. If the resistors are connected next to each other, with both ends of each resistor directly connected, they are in parallel.
For example, let's consider a circuit with three resistors: R1, R2, and R3. If R1 is connected to R2, and R3 is connected separately, with both ends of R1 directly connected to both ends of R2, and both ends of R3 directly connected to the same points, then R1 and R2 are in series, and R3 is in parallel with the combination of R1 and R2.
By assessing the circuit diagram and analyzing the connections between the resistors, we can identify the series and parallel sections of a combination circuit. So therefore in order to identify the series and parallel sections of a combination circuit, we need to examine the circuit diagram and determine whether the resistors are connected in series or in parallel.
