Circuit Lab Flashcards
To monetize all you need to know for the Circuit Lab competition in science Olympiad 2019
Volta
Invented an electric battery, Ferst source of DC current
Faraday
Magnetic induction
Tesla
Invented the ferst AC motor, , made an AC generation and, transmission technology
Ohm
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
Hertz
Proved the existence of the electromagnetic waves theorized by James Clerk Maxwell’s electromagnetic theory of light
Electric charge field’s
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
Hazards from static electricity-
are that for instance, the air is usually thick with fine flammable grain-dust particles which static electricity can ignite
Coulomb’s law
Have a law of physics for quantifying the amount of force which stationery electrically charged particles repel or attract each other
Capaity
Is the ratio of the charge in a system to the corresponding charge in its eletric potential (simbol C)
DC characteristics
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.
DC uses
Low voltage applications like, charging batteries, automotive application, aircraft applications, and other low voltage, low current applications.
DC hazards
It can affect the ability to the heart to pump 4 blood, resulting in brain damage and eventually cardiac arrest, at high levels.
AC characteristics
Amplitude, cycles, frequency, peak to peak, and RMS
AC sources
Steam turbine generator, AC generator
AC uses
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.
AC hazards
Same as DC
Concepts and units of current
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”
Voltage
A electromotive force potential difference expressed in volt’s
Resistance
The ability not to be affected by something, especially adversely
Power
Supply (a device) with mechanical or electrical energy
Energy
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.
What does vrip stand for
V R I P
o O A W
l h m a
t m p t
s s s t
sMagnetic poles/field
A region around a magnetic material or a moving electric charge within which the force of magnetictisom act’s
Electromagnets
A soft metal core into a magnet by the passage of electric current through a coil surround it.
Transformers
An apparatus for reducing or increasing or the voltage of an alternating current
Motors/generators
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.
Right-hand rule
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.
Simple measurements
Standards are special object that are to make measurements terms of fixed units, can compare that measurements to anthing elts that is also measured with metre stick.
Constructions
Is the process of constructing a building or infrastructure. Construction differs form of measurement. A metre ststis an example of a standard. When you measure something
