Ima Ch.4: Magnetism & Electricity

Front 1

What are two types of magnets?

Back 1

those found in nautrally/
loadstone those that are made synthetically/magnetite.

Front 2

What are the three particles atoms consist of?

Back 2

Protons, Neutrons, Electrons

Front 3

Protons:

Back 3

bears a postive charge and reside in the atoms nucleus

Front 4

Neutrons:

Back 4

reside also in the neucleus; they do not carry a distinctive charge and therefore are classifed as neutral.

Front 5

Electrons:

Back 5

which exhibit a negative charge , but orbits around the neuclus of the atom.

Front 6

Electromagnetics:

Back 6

wires coiled to increase the power of magnetic fields

Front 7

What are the two varieties of electricty?

Back 7

Static and Current

Front 8

Static Electricity:

Back 8

is present when an imbalance of positive and negative particles exists between two forms of matter.

Front 9

Current Electricity:

Back 9

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.

Front 10

Any material allowing for the smooth flow of charged particles is known as a ________.

Back 10

Conductor

Front 11

Alternating Current (AC):

Back 11

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.

Front 12

Direct Current (DC):

Back 12

Current flowing in only one acknowledged direction

Front 13

Current Elecricity:

Back 13

steady stream of electrons from atom to atom

Front 14

Static Electricity:

Back 14

Unequal Postive & negative particles; creates a flow of electricity.

Front 15

Flux:

Back 15

field around particles that cause attraction & repulsion; typical two poles-north & south.

Back 29

Unequal Postive & negative particles; creates a flow of electricity.

Front 30

Flux:

Back 30

field around particles that cause attraction & repulsion; typical two poles-north & south.

Front 31

How many poles are there if electrons pass through a straight wire?

Back 31

One pole.

Front 32

How do we do to generate two poles?

Back 32

coling a wire tightly allows for 2 poles; not magnetic until electrons flow--Audio and video recordings.

Front 33

Circuit:

Back 33

unbroken path current travels to produce work.

Front 34

What type of current is easy to distribute?

Back 34

AC (Alternating Current).

Front 35

Alternating Current can be ______________.

Back 35

Transformed and convertible.

Front 36

What century did the DC electricity come into pan?

Back 36

19th century.

Front 37

Who improved the the efficiency capabilities of existing DC equipment?

Back 37

Nichola Tesla

Front 38

Who supported AC? Who supported DC?

Back 38

Nichola Tesla; Thomas Edison.

Front 39

How did Thomas Eddsion bash AC electricty?

Back 39

He electrocuted to prove that AC was dangerous.

Front 40

Cycle:

Back 40

is the amount of times electrons change direction in a given timeframe.

Front 41

What is the AC cycle is the U.S? How is it understood?

Back 41

60Hz; 60 conversions per second.

Front 42

What did Nichola Tesla establish the most efficient pace to execute AC production.

Back 42

60Hz

Front 43

What was Europe's standard cycle ? Why?

Back 43

50hz because it is more compatible with the meteric system.

Front 44

What is the common residential voltage electrical outlets feature in the U.S?

Back 44

120-volt

Front 45

How is one sine of wave of AC traveling channels, oscillating from levels of -170 to 170 volts, classified as?

Back 45

Single Phase Power.

Front 46

What is the average Single Phase power?

Back 46

120 volts.

Front 47

What is RMS and what does it stand for?

Back 47

The Root-Mean-Square is a strength rating average of at 120 volts.

Front 48

What do the smaller of the upper two vertical slots of an outlet designate? How much do this slot feed?

Back 48

"HOT" ; 120-volt AC signal to the device plugged in.

Front 49

What does the longer of the two vertical slot designate?

Back 49

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.

Front 50

What is the single round port on the outlet?

Back 50

The "gound", which basically grounds a current crucial for overall safety; a hazardous device that can defuse electricity into the Earth.
