Series and Parallel Circuit Simulator
Quick answer: Series elements carry the same current and their resistances add. Parallel branches share voltage and their conductances add. Mixed networks are simplified stage by stage or solved from the connected circuit.
User job: Make current and voltage relationships visible in an editable network.

Worked example
Two 1 kΩ resistors in series equal 2 kΩ. Two 1 kΩ resistors in parallel equal 500 Ω. At 10 V, those networks draw 5 mA and 20 mA respectively.
Step-by-step workflow
- Choose series, parallel or mixed topology
- Enter source and resistor values
- Calculate the equivalent resistance
- Run the DC operating point
- Compare branch current and power
Outputs and deliverables
- Editable network
- Equivalent-resistance steps
- Node-voltage results
- Branch-current results
- Power comparison
Quality checks before issue
- Ground/reference is defined
- Every branch is actually connected
- Units are consistent
- Resistor power is checked
- Source limits are considered
Current product and engineering boundaries
- The example assumes linear resistors.
- Temperature and tolerance are omitted from nominal values.
- Parallel source or nonlinear network rules require a more complete model.
