Components of an electrical
circuit can be connected to one another in several ways, such as to arrange the
circuit to form either a series circuit, shown in Figure 1, or a parallel circuit,
shown in Figure 2. The main difference between a series circuit and a parallel
circuit is how they are arranged (1). A series circuit is a circuit in which
loads are connected one after another in a single path; where as the loads of a
parallel circuit are connected side by side (1). For example, if the first light
bulb of three light bulbs connected in a series circuit was to blow out, all
other light bulbs would fail to light; thus rendering them obsolete. This is
because when the first light bulb fails, the serial electron flow through the
circuit stops as all loads are connected in a single path (1). This would be
different in a parallel circuit set up due to the fact that it allows electrons
to spill into other paths (3). If the first light bulb of three light bulbs
connected in a parallel circuit were to blow out, all other light bulbs would
remain working. Clearly, the use of parallel circuits is more effective.

An oddity to me occurred during
this assignment as I noticed that the energy ball worked better with some
people more than they did with others. I believe the reason for this is that
humans are natural semi-conductors. Semi-conductors are substances, usually
solid chemical elements or compounds, that can conduct electricity under
certain conditions (2). This allows the human body to be suitable moderator of
electrical current (2). This explains why humans receive static electric
shocks. A common example of a semi-conductor is silicon (4). Over 50% of
the human body is made up of water (5). Much of this water is ionized, due to a
vast amount of it being salt water which dissociates into ions when in a solution
(6). Because it is ionized, it is able to conduct. A method one could use to
avoid conducting electricity would be to wear an insulator. If one wished to
conduct electricity, they could charge by friction by rubbing their socks
across carpet (1).

As any other assignment, this
energy ball assignment worked with several learning skills: responsibility, organization,
independent work, collaboration, initiative, and self-regulation. I took responsibility
for what would by my first report in this class by making sure that my work was
well done. I kept organized throughout this assignment, which aided me in my
final independent effort of this blog entry. Working in a group, and eventually
the entire class, made me realize that I am more comfortable working with others.
Through the classroom exercise I also learned that I am better working hands-on
as it was more visual. Taking initiative is a problem for me because I seldom
feel confident in my work, but through this assignment I took initiative to
research circuits and electricity for a solid understanding on the topics. I
self-regulated by doing a sufficient amount of work on this report daily to ensure
a quality completion of my tasks by the due date.
