Sources in parallel, open circuits, and short circuits
Batteries wired side by side, a broken wire, a stray blob of solder: each changes a circuit in ways that the plain series and parallel rules handle only if you know exactly what an open and a short do. This topic pins those two conditions down and shows when sources may share a load.
In this topic
- Two extreme conditions
- Identical voltage sources in parallel
- Unequal sources in parallel
- Worked example: mismatched batteries
- The open circuit
- Worked example: resistors beside a gap
- The short circuit
- Worked example: a resistor shorted out
- Spotting opens and shorts in a network
- Common mistakes to avoid
- Key takeaways
