Predict the quantity of electricity

Skills: Analyse

Statement

Only the display of A1 is visible. If this circuit runs for 2 min, what quantity of electricity will have gone through A1?

Answer; the Q counter of the simulated time (×60) gives the same value, if you want to make sure.

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

3 hints from Bastaya available in the lab
Solution

Q = I × t = 1 × 120 = 120 C.

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.
