EMAGS 2 Flashcards
The inductance is in series with the linear resistance in a transmission line due to inductance is a quantity resulting from interactions of:
line current and magnetic fields
All of Maxwell’s Equations are his works
False
To determine the “D”-field, given the electric field, the permittivity of the material to which the electric field passes is multiplied to the “D”-field
False
Wired media has the limitation of distance but is less susceptive to atmospheric noise being insulated
True
Which of the following states that “the total magnetic flux coming out or through a closed surface is zero”?
Gauss Law for magnetism
The transmission line can be represented as a circuit with
RLC elements
These are usually solid linear conductors that physically connect the transmit and received signals
Wired Media
The most important part of the communications system due to its linking role
Transmission Media
The changing electric field effect in one of Maxwell’s Equations was manifested through a dischargine capacitor’s electric field
True
The “c” for the speed of light stands for “constant”
False
The inductor stores voltage.
False
These are highly susceptive to environmental interference.
Wireless Media
Electromagnetic waves travels in free space in which manner?
The “E” and “B” fields perpendicular and at light speed
All of the Maxwell’s equations are for electric quantitities
False
Due to parallelism, in the same way that electric charges can exist separately either be a positive or a negative charge, we can say that the magnetic poles can exist separately either be a north pole or a south pole
False
