Exercise from the chapter "Ohm's law & resistance"

The chips

Level 1 of 5 · Skills: Build

Statement

The red lead reaches hole A2, but the resistor starts at E2: the loop is open.

Click Jumper chip in the palette (or key C), then drag on the board from A2 to E2: a line of chips joins the holes. Each chip bridges two neighbouring holes, with no resistance.

2 hints from Bastaya available in the lab
Solution

Four chips join A2, B2, C2, D2 and E2: those five holes are now a single circuit node.

How does it work?

The perfboard: each big hole is a circuit node. You push a single leg of a component (resistor, lamp...) into it. The 4 small holes around it are connected to it: that is where chips and leads plug in.

  1. Drag a component onto the board: it snaps onto the grid. R rotates it.
  2. To join neighbouring big holes, click Jumper chip in the palette (or C) then drag on the board: a line of chips is laid at once. Bridged holes become a single node.
  3. For long links and for the power supply (placed next to the board), drag a lead from one big hole to another (or to a terminal).
  4. As soon as a loop is closed, the circuit is solved in real time (Ohm + Kirchhoff) and the diagram follows.
  5. Zoom with the wheel (or + / −, two-finger pinch); drag the background to pan, 0 fits the board. The + buttons around the board add a row or a column.
