Two faults

Skills: Build

Statement

Two faults hide in this R1 ∥ R2 circuit controlled by K1.

Fix both to get back to the target diagram, current included.

3 hints from Bastaya available in the lab
Solution

Switch open: no branch is supplied. Chip above the right leg of R2 missing (F3-F4): even with K1 closed, only R1 conducts. Both fixed: I = 9 V / 150 Ω ≈ 60.1 mA.

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.
