en.wikipedia.org/wiki/Series_and_parallel_circuits

Components of an electrical **circuit** or electronic **circuit** can be connected in many
different ways. The two simplest of these are called **series** and parallel and ...

Let's start with a **series circuit** consisting of three resistors and a single battery:
The first principle to understand about **series circuits** is that the amount of current
...

As mentioned in the previous section of Lesson 4, two or more electrical devices
in a **circuit** can be connected by **series** connections or by parallel connections.

The parallel circuit has very different characteristics than a **series circuit**. For one,
the total resistance of a Parallel Circuit is NOT equal to the sum of the resistors ...

www.swtc.edu/ag_power/electrical/lecture/series_circuits.htm

A **series circuit** is one with all the loads in a row. There is only ONE path for the
electricity to flow. If this circuit was a string of light bulbs, and one blew out, the ...

Let's make our circle a little bit more complicated now. So let's say I have a battery again, and let me do it in a different color just for variety. That's the positive ...

Where four, five or even more resistors are all connected together in a **series**
**circuit**, the total or equivalent resistance of the circuit, RT would still be the sum of
...

That's half the battle towards understanding the difference between **series** and
parallel. We also need to understand how current flows through a **circuit**.

**Series circuits**. A **series circuit** is one that has more than one resistor, but only
one path through which the electricity (electrons) flows. From one end of the cell ...
