Question 4

Ohm

Answer 4

Made ohm’s law. Which states that the current flow through a conductor is directly proportional to the potential difference (voltage) and inversely proportional to the resistance

Question 5

Hertz

Answer 5

Proved the existence of the electromagnetic waves theorized by James Clerk Maxwell’s electromagnetic theory of light

Question 6

Electric charge field’s

Answer 6

Physical properties, it causes it to experience a force when placed have an electromagnetic field. 2 types of electric charges, positive and negative (commonly carried by protons and electrons respectively)
Like charges repel and unlike attract

Question 7

Hazards from static electricity-

Answer 7

are that for instance, the air is usually thick with fine flammable grain-dust particles which static electricity can ignite

Question 8

Coulomb’s law

Answer 8

Have a law of physics for quantifying the amount of force which stationery electrically charged particles repel or attract each other

Question 9

Capaity

Answer 9

Is the ratio of the charge in a system to the corresponding charge in its eletric potential (simbol C)

Question 10

DC characteristics

Answer 10

Composed of moving charges. Constantan in time. Flowing in one direction. Made from ponersorses such as, batteries, power supplies, DC generators, and photovoltaic devices like solar cells.

Question 11

DC uses

Answer 11

Low voltage applications like, charging batteries, automotive application, aircraft applications, and other low voltage, low current applications.

Question 12

DC hazards

Answer 12

It can affect the ability to the heart to pump 4 blood, resulting in brain damage and eventually cardiac arrest, at high levels.

Question 13

AC characteristics

Answer 13

Amplitude, cycles, frequency, peak to peak, and RMS

Question 14

AC sources

Answer 14

Steam turbine generator, AC generator

Question 15

AC uses

Answer 15

It can change from low to high and back again at any point allowing us to send things at low voltage but switch to them too high when they get to their destination.

Question 16

AC hazards

Answer 16

Same as DC

Question 17

Concepts and units of current

Answer 17

The Marco unit of charge in electrical in coulomb C . A definition of it is, “the charge passing an arbitrary fixed point when a current of 1 amp”

Question 18

Voltage

Answer 18

A electromotive force potential difference expressed in volt’s

Question 19

Resistance

Answer 19

The ability not to be affected by something, especially adversely

Question 20

Power

Answer 20

Supply (a device) with mechanical or electrical energy

Question 21

Energy

Answer 21

Is the quantitative proprietary that must be transferred to an object to perform work on, or to heat, the object. Energy is a conserved quality; the law of conservation of energy stats that energy can be converted in form, but not created or destroyed.

Question 22

What does vrip stand for

Answer 22

V          R         I            P

A region around a magnetic material or a moving electric charge within which the force of magnetictisom act’s

Question 24

Electromagnets

Answer 24

A soft metal core into a magnet by the passage of electric current through a coil surround it.

Question 25

Transformers

Answer 25

An apparatus for reducing or increasing or the voltage of an alternating current

Question 26

Motors/generators

Answer 26

A machine, especially one powered by electricity or internet combustion, that supplies motive power for a vehicle or for some other device with moving parts.

Question 27

Right-hand rule

Answer 27

In mathematics and physics, the right-hand rule is a Common mnemonic for understanding notation conventions for vectors in three dimensions. Most of the various left- and righ-hand rulea arise from the fact that three axes of 3-dimensional space have two possible orientations. This can be seen by holding your hands together, palm up, with the fingers curled.
