Solved exercise · level 2 of 5

Measure then compute Q

Skills: Measure, Calculate

Statement

Read the current on A1, then start the simulated time (Measurements panel) and let it run for 10 s.

What quantity of electricity went through A1 in that time? Then compare with the Q counter.

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

3 hints from Bastaya available in the lab
Solution

I = 2 A; Q = I × t = 2 × 10 = 20 C. The simulated-time Q counter accumulates exactly I × t.

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.
