Solved exercise · level 2 of 5

Build a series circuit and read a partial voltage

Skills: Build, Analyse

Statement

Build R₁ = 22 Ω, R₂ = 12 Ω and R₃ = 39 Ω in series on G (12 V), setting their values in the inspector. Then compute the voltage across R₂ and enter it (the Measurements panel will confirm it).

Parametric exercise: the values change with every draw; these are one example.

3 hints from Bastaya available in the lab
Solution

I = 12 / (22 + 12 + 39) = 164 mA; u₂ = R₂ × I = 1.97 V. The sum u₁ + u₂ + u₃ gives back 12 V.

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.
