1. Circuits in Series and Parallel

2. Circuits in Series and Parallel
Circuits can be built so that the current has one or more
paths to travel along.

3. Series Circuits
A circuit in SERIES has only 1 path to travel along.

5. Series Circuits
To measure current, an ammeter is always connected
in series to the part being measured.
Example:

6. Parallel Circuits
A circuit in PARALLEL has branched paths the
electricity may split-up into.
Example:

7. Parallel Circuits
To measure voltage, a voltmeter is always connected in
parallel to (surrounding) the part being measured.
Example:
Here, the voltmeter is measuring the voltage of the source.

8. Circuits in Series and Parallel
You can also have a circuit with components that are
both in series and in parallel.
