What are two types of magnets?
those found in nautrally/
loadstone those that are made synthetically/magnetite.
What are the three particles atoms consist of?
Protons, Neutrons, Electrons
Protons:
bears a postive charge and reside in the atoms nucleus
Neutrons:
reside also in the neucleus; they do not carry a distinctive charge and therefore are classifed as neutral.
Electrons:
which exhibit a negative charge , but orbits around the neuclus of the atom.
Electromagnetics:
wires coiled to increase the power of magnetic fields
What are the two varieties of electricty?
Static and Current
Static Electricity:
is present when an imbalance of positive and negative particles exists between two forms of matter.
Current Electricity:
is created by the passage of charged particles (electrons) on departing one atom for another.
An electrical circuit is an unbroken path along which an electrical current may securely flow.
Any material allowing for the smooth flow of charged particles is known as a ________.
Conductor
Alternating Current (AC):
When the flow across a conductor is seen to alternate-or travel in one direction for a part of cycle and reverse for the remainder.
Direct Current (DC):
Current flowing in only one acknowledged direction
Current Elecricity:
steady stream of electrons from atom to atom
Static Electricity:
Unequal Postive & negative particles; creates a flow of electricity.
Flux:
field around particles that cause attraction & repulsion; typical two poles-north & south.

How many poles are there if electrons pass through a straight wire?
One pole.
How do we do to generate two poles?
coling a wire tightly allows for 2 poles; not magnetic until electrons flow--Audio and video recordings.
Circuit:
unbroken path current travels to produce work.
What type of current is easy to distribute?
AC (Alternating Current).
Alternating Current can be ______________.
Transformed and convertible.
What century did the DC electricity come into pan?
19th century.
Who improved the the efficiency capabilities of existing DC equipment?
Nichola Tesla
Who supported AC? Who supported DC?
Nichola Tesla; Thomas Edison.
How did Thomas Eddsion bash AC electricty?
He electrocuted to prove that AC was dangerous.
Cycle:
is the amount of times electrons change direction in a given timeframe.
What is the AC cycle is the U.S? How is it understood?
60Hz; 60 conversions per second.
What did Nichola Tesla establish the most efficient pace to execute AC production.
60Hz
What was Europe's standard cycle ? Why?
50hz because it is more compatible with the meteric system.
What is the common residential voltage electrical outlets feature in the U.S?
120-volt
How is one sine of wave of AC traveling channels, oscillating from levels of -170 to 170 volts, classified as?
Single Phase Power.
What is the average Single Phase power?
120 volts.
What is RMS and what does it stand for?
The Root-Mean-Square is a strength rating average of at 120 volts.
What do the smaller of the upper two vertical slots of an outlet designate? How much do this slot feed?
"HOT" ; 120-volt AC signal to the device plugged in.
What does the longer of the two vertical slot designate?
The longer slot is electrically "neutral" amd provides an open electrical pass from the appliance pluf to the electricity source, eventually linking to the ground at the electrical panel.
What is the single round port on the outlet?
The "gound", which basically grounds a current crucial for overall safety; a hazardous device that can defuse electricity into the Earth.
