Simple Circuit
A
simple circuit contains the minimum
things needed to have a functioning
electric circuit
Requirements

A source of electrical
potential difference or
voltage. (typically a
battery or electrical
outlet)
Requirements

A conductive
path which
would allow for
the movement of
charges.
(typically made
of wire)
Requirements

An electrical resistance
(resistor) which is loosely
defined as any object that
uses electricity to do
work. (a light bulb, electric
motor, heating element,
speaker, etc.)
A Simple Circuit
The battery or source is represented by an
escalator which raises charges to a higher level
of energy.
A Simple Circuit
As the charges move through the resistor
(represented by the paddle wheel) they do work on
the resistor and as a result, they lose energy.
A Simple Circuit
By the time each charge makes it back to the
battery, it has lost all the energy given to it by the
battery.
A Simple Circuit
As the charges move through a wire, they lose no
energy (assuming the wires are short and are a
good conductor).
A Simple Circuit
The potential drop ( - potential difference) across the resistor is the same as
the potential rise ( + potential difference) across the battery. This
demonstrates that a charge can only do as much work as was done on it by the
battery.
A Simple Circuit
The charges are positive so this is a representation of
Conventional Current (the apparent flow of positive
charges)
A Simple Circuit
The charges are only flowing in one direction so this
would be considered direct current ( D.C. ).
