Parallel Connections: Wires and Nodes
Explore eight drawings of parallel resistors: Diamond, Diagonal, Folded, Fan, Ladder, Triangle, Twin rails and Stepped. Gather every starting end at a single node a and every finishing end at a single node b while keeping each branch connected to the same two nodes.
Cómo usar esta simulación
- Choose one of eight circuit shapes containing three or four resistors
- Use Gather the ends, Pause and Fold back, or move the progress slider
- Adjust playback speed to 0.5×, 1× or 2×
- Use Show nodes to hide or reveal the colors and node labels
- Switch between English and Arabic
Qué observar
- The starting contacts merge into one point a and the finishing contacts into one point b
- Each resistor keeps its original a-to-b connection throughout the transformation
- In Ladder, all four resistors stay horizontal and stationary while the contacts gather on the left and right
- The final connection is parallel even when the original drawing looks different
La física detrás
Every point joined by an uninterrupted ideal wire belongs to the same electrical node. Resistors are in parallel when each one connects between the same two nodes, a and b. Their positions, orientations and the lengths of the drawn wires do not determine the connection. Each parallel branch therefore has the same potential difference between its ends. The wires in this simulation have zero resistance. Wire crossings connect only where a junction dot is shown.
