Parallel: the voltage

Skills: Know

Statement

In a parallel circuit, the voltage across each branch is...

  1. The same for all branches
  2. Shared in proportion to the resistances
  3. Larger in the most resistive branch
  4. Zero if the resistances are equal
2 hints from Bastaya available in the lab
Solution

The branches join the same two nodes: they all see the same voltage.

How does it work?

Each big hole is a circuit node: you push one leg of a component into it. The 4 small holes around it are connected to it: chips and leads plug in there.

  1. Place a component Drag it from the palette: it snaps onto the grid. R rotates it.
  2. Bridge neighbouring holes Pick the jumper chip (or C) and drag on the board: bridged holes become a single node.
  3. Draw a lead For long links and the power supply: from one big hole to another, or to a terminal.
  4. Close the loop The circuit is solved live (Ohm, Kirchhoff) and the diagram follows.
