Two capacitors in parallel

Skills: Know

Statement

Two capacitors of 10 µF and 22 µF in parallel have an equivalent capacitance of...

  1. 32 µF
  2. 6,9 µF
  3. 12 µF
  4. 220 µF
2 hints from Bastaya available in the lab
Solution

In parallel capacitances add up (unlike resistances): 10 + 22 = 32 µF.

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.
