Compare alternating current with direct current?
Alternating current changes direction on a set frequency such as 50 Hz, 60 Hz or 400 Hz. Direct current always flows in one direction.
Why high frequency signal is more affected by noise compare to low frquency signal?
AS FREQUENCY INCREASE THE BANDWIDTH INCREASE. AS WE KNOW NOISE HAVE LARGER BANDWIDTH. SO ITS AFFECT HIGH FREQUENCY SIGNAL. BUT LOW FREQUENCY SIGNAL HAVE LOW BANDWIDTH SO IT IS LESS AFFECTED BY NOISE. ALSO WE KNOW QUALITY FACTOR= CUTOFF FREQUENCY / BANDWIDTH. SO AS FREQUENCY INCREASE B.W. INCREASE SO QUALITY DEGRADE. CUTOFF FREQUNCY AND THE TERM FREQUENCY (USED HERE) IS DIFFERENT. CUTTOFF FREQUNCY IS USED IN FILTER. PRABIR KUMAR SETHY prabirsethy.05@gmail.com
How does the peak value of an alternating voltage compare to its quoted value?
The quoted value is usually RMS value, i.e it is lesser than the peak value of the voltage, therefore the peak value is sqrt(2) times the quoted value. (it is a sine wave)
How to compare two array list when one array list always fluctuate rows?
I am creating one array list and attempting to equals to another array list, the reader through CSV file. CSV row is not in the same order, changing everything when downloading. I tried with equals and compare to but both fail due to row fluctuations. How do I compare? Apart from row number, everything is the same .

What happens to the direction of the magnet field about a straight section of wire when the direction of the current is reversed?
In that case, the magnetic field caused by the current would also be reversed. As for the wire itself, it would feel a force in the opposite direction, due to the interaction of the magnetic fields.
Compare alternating current with direct current?
Alternating current changes direction on a set frequency such as 50 Hz, 60 Hz or 400 Hz. Direct current always flows in one direction.
How do you compare magnetic moments of two magnets using deflection magnetometer?
introduce it in magnetic field.
How do the wavelength and frequency of red light compare to the wavelength and frequency of blue light?
very nice answer.
What are the applications of deflection magnetometer?
To compare the magnetic moments of two different bar magnets. To check the earth magetic moment. To verify inverse square law . Compare earth's magnetic induction . determine the horizontal component of the earth's magnetic induction .
How does the frequency of the waves compare in the two diagrams?
use an ruler
What is a graph used to compare categories of data?
frequency table
How does frequency of the ultrasonic waves of the echo from the stationary object compare with frequency of the ultrasonic waves of the probe?
the frequencies are same.
How can scientists tell when changes occur in earths magnetic field?
Scientists follow the magnetic field lines of the earth and measure them regularly. They will compare the earlier measurements and note the changes in position of the magnetic axis and decide if it is changing or not! Also if there are sudden changes observed in magnetic field lines bec of solar flares from sun. Magnetism is an interesting chapter! learn more by watching and subscribing to this space @PhysicsFusion-sm3tr Hope this helps
Which wavelength possesses the lowest frequency?
Provided you compare waves that all have the same speed, the longest wave has the lowest frequency.
How do the frequencies of blue light or red light compare?
The frequency of blue light is roughly double the frequency of red light.
How do infrared waves compare with gamma rays?
Much lower frequency.
How does the frequency of light compare to the frequency of sound?
-- The highest frequency of sound audible to the human ear is of the order of 20,000 Hz.-- The lowest frequency of light visible to the human eye is of the order of 375,000,000,000,000 Hz.
