FIG. 1
Note: For the purpose of demonstration, below diagrams are general electrical circuits in
our daily life only. They are not circuits for Connex kits.
The circuit shows in fig.1 is a series circuit. It involves series connection.
As electricity flows in a single path, the current flow through each device will be the same.
However, if any one of the device is broken, the circuit will be disconnect and cannot
function.
EDUCATIONAL HINTS
Series and Parallel connection
The circuit shows in fig.2 is a parallel circuit. It involves parallel connection.
Each electricial device is connected in parallel. If one device is broken, the other devices
can still work.
