The simple questions assume ideal wires and components with the stated resistance.
Keep these ideas clear
Use ideal models carefully
The simple questions assume ideal wires and components with the stated resistance.
Describe connections
Series components share a path; parallel branches connect across the same two nodes.
Two useful examples
Ideal resistors in series carry the same
current
current
Ideal parallel branches connected across the same nodes share the same
potential difference
potential difference
Explain it without looking
- Why is a circuit diagram more reliable than saying two resistors are next to each other?
