Current direction

Skills: Know

Statement

By convention, outside the generator, current flows...

  1. From the + pole to the − pole
  2. From the − pole to the + pole
  3. In both directions at once
  4. It depends on the resistance
2 hints from Bastaya available in the lab
Solution

Conventional direction: from + to − outside the generator; electrons go the other way.

Circuit diagram CEI 60617

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.
