Electrical Circuit An _________ ________ consists of a power source, conductors, and load
simple curcuit A ________ ________ consists of only one energy source, one conductor, and one load.
series curcuit A simple ________ ________ has at least two loads. The current flows along a single path and the
components are located one after another along this path
parallel curcuit A simple ________ _______, the voltage applied to each branch is the same
direction of current what do arrows indicate
electron flow Inside a DC power source (such as a battery) the electrons travel from the positive
terminal to the negative. Electrons traveling outside of the power source (a circuit)
electrons travel from the negative to the positive terminal.

continuity The continuous effective contact with all parts of an electrical circuit to give it a high
conductance (low resistance).
direct current and alternating current What are two types of electric current?
power source In any completed circuit, it takes a force to push the electrons through the ______ ______,
conductor, and load. The two types of force to push the electrons of electric current are
direct current (DC) and alternating current(AC).
load 1) Power output such as a power plant.
(2) A device to which power is delivered.
(3) The demand upon the operating resource of a system such as a telephone exchange
system or circuit of garden lights.
direct current The polarity from _________ ______ power sources never changes; that is, the current flows out
of the negative terminal of the power source in the same direction
alternating curent power sources produce a voltage and current that has a constant change in polarity and
magnitude at a constant frequency, back and forth in a conductor. ________ ________ flow is
produced by a generator or an alternator.
frequency The rate of flow reversal is called
60 cycles per second (60 Hz) Nearly all AC power systems in U.S.A. operate at a frequency of
AC waveforms When an alternator produces AC voltage, the voltage switches polarity over time, but
does so in a very particular manner. When graphed over time, the "wave" traced by this
voltage of alternating polarity from an alternator takes on a distinct shape, known as a
sine wave.
conductance _____________ is the property of metal that permits current to flow
1/resistance =conductance
