•Electrons are the charge carriers that
flow in an electrical circuit from the
negative to positive terminals.
NOTE: Electrons have a negative charge…. Like
charges repel, opposites attract) giving rise to
an electric current.

Representation of Current:

76. Circuits
•A circuit is a pathfor current to flow
•Three basic kinds of circuits
•Open–the path is brokenand interrupts current flow
•Close–the path is completeand current flows were it is
intended
•Short–the path is corruptedin some way and current
does not flow were it is intended

116. RESISTORS
Resistance?
A resistor is an
electronic component
used to oppose flow of
electron with a fixed
electrical resistance or
variable.
Resistance is the property of
the material, which oppose
how much the flow of current
to passthrough it.
