Why amplitude modulation is used for video transmission?
IF we use frequency modulation for transmitting video signal this can cause phase shifting .and eyes can percieve this distortion effect easly . and requires more bandwidth to send the signal .Color levels are adjusted by amplitude in TV .So it s more logic to use Amplitude modulation .
What are the disadvantages of series capacitors in transmission lines?
The series capacitors can be the cause of overcompensating on the power line and thus cause the following problems:- a) Over voltages on the line when connected loads are smaller than the rated loads and this can damage the transformers and capacitors b) Ferro-resonace phenomenon can cause very high volatges again can be damaging c) The fault level of the poweer system will increase and if not considered in the design, the fault current could exceed thedesign limits.
Can a cut electrical wire cause a fire?
If the exposed wire grounds out and a great amount of heat is produced then yes a fire could start under this condition. Remember overhead transmission wires are exposed wires but are well insulated from ground so as not to have the above scenario happen.
Why is a cracked plug socket can cause a potential fire hazard?
The cracked plug can cause the wires to spark and cause a fire. When the wires are plugged into it where the crack is the wires can touch the socket and cause the fire.
What phase of DMAIC will you identify the root cause of the problem?
In the analyze phase of DMAIC you are able to identify the root cause of the problem.
What can cause auroras and disrupts satellite transmission?
ultraviolent radiation
Can sunspots cause auroras and disrupt satellite transmissions?
Yes, sunspots can cause auroras by releasing solar flares and coronal mass ejections that interact with Earth's magnetic field. These events can also disrupt satellite transmissions by creating geomagnetic storms that interfere with satellite communication signals.
What problems can be caused by Auroras?
Auroras can disrupt satellite communication and navigation systems, cause power outages by inducing electrical currents in power grids, and create radio signal interference which can impact communication systems.
Gusts of solar wind can cause?
Gusts of solar wind can cause geomagnetic storms on Earth, which can disrupt satellite operations, power grids, and communication systems. These gusts can also produce auroras visible at high latitudes.
Do solar flares from the sun cause auroras near earths poles?
Magnetic storms unleashed by solar flares can cause auroras, but all solar flares don't cause auroras.
What cause Earth's auroras?
The suns radiation hitting our atmosphere
What can gusts of solar winds cause?
Gusts of solar winds can cause disruptions to Earth's magnetic field, leading to geomagnetic storms and auroras. They can also interfere with satellite operations, power grids, and communication systems.
Are Auroras a cause of light pollution?
No, the Aurora is a result of space weather.
What can cause auroras near earth poles?
Auroras near Earth's poles are caused by solar wind particles interacting with the Earth's magnetic field. When these charged particles from the sun collide with atoms and molecules in the Earth's atmosphere, they create light emissions, producing the colorful auroras. The Earth's magnetic field funnels these particles towards the poles, resulting in the concentration of auroras in these regions.
Does disturbances in Earth's magnetic field cause auroras?
Not quite but they would affect the auroras. The physical, light-emitting reaction is that between charged particles from the Sun and the field.
What damage does a solar flare cause?
Solar flares can disrupt radio communications, GPS systems, and power grids on Earth. They can also pose a hazard to astronauts in space, as they can increase radiation levels. Additionally, solar flares can create stunning displays of auroras in the Earth's atmosphere.
Auroras are the result of energy from solar flares?
Auroras are caused by solar wind particles interacting with Earth's magnetic field, not solar flares directly. Solar flares can cause an increase in solar wind activity, which can lead to more intense auroras.
