Description: See how two components are assembled in series or in parallel. Observations of luminosities in the case of bulbs ...

Definitions:
Series :

- the number of components has an influence on their operation;
- a failure prevents the other devices from functioning;
- the order doesn't matter.
Parallel :

- The devices are connected in parallel when they are connected to each other. They form 2, 3,… loops;
- in parallel, neither the number nor the state of the components influences the functioning of a single one.
