1. In a series circuit, the
is shared between the components, but the
is the same. In a parallel circuit, the
is shared between the components, but the
is the same for each branch.
2. If a set of chistmas tree lights are wired in
, and one globe "blows", then the other globes will be on.
If a set of chistmas tree lights are wired in
, and one globe "blows", then the other globes will be off.
3. Household wiring is like a big
circuit with many branches.
