How is a DC waveform produced from the output terminals of a DC generator?
you cant
Does changing the number of magnets in a generator affect the amount of energy produced?
Yes
Is it true that Gene maps are produced by monitoring the frequency of crossing-over between genes?
It is true that gene maps are produced by monitoring the frequency of the crossing-over between genes. Their changes and adaptations are use in the construction of a gene map.
What is the radiation source for microwaves waves?
Microwave frequency radio waves are usually produced by a MAGNETRON.
How does electricity come to your house?
Electricity is produced in power station and then passed through to a generator. The generator passes the electricity through lines and then to another generator. it is again passed through lines and then to a primary customer which may be an industry or an electricity company. It is then passed on to a secondary customer through power lines through to your house.
Explain about magnetostriction generator in physics?
Magnetostriction generator is used to produce ultrasonic waves. It consist of a ferromagnetic rod and an electronic oscillator.when alternating current is produced by the electronic oscillator the rod experience a small change in length with the production of ultrasonic waves...
Why not ultrasonic be produced by passing high frequency alternating current through speaker?
The ability of a speaker to produce ultrasonic output when driven with high frequency AC depends on the design (intent) of the speaker. Typical audio speakers are not designed to go ultrasonic - the cone's mass and resonate frequency just won't support it. Also, the coil reactance is too high for ultrasonic waves so they cannot be produced.
How 50Hz frequency is selected for a generator design?
Frequency is a function of engine speed and the number of poles in the generator end. For instance, a speed of 1500 RPM turning a four-pole generator will produce 50 hz. The formula is: Frequency = (poles/2) * (RPM/60) From the formula, you can see that the same frequency would be produced by a two-pole generator spinning at 3000 RPM.
Whether the sound produced by a seconds pendulum is infrasonic or ultrasonic?
Infrasonic denotes any sound that is at a frequency below the human capability of hearing, this is around 5-25Hz. Ultrasonic on the other hand is, conversely, a frequency that is above the human hearing range (over 20,000Hz).
Explain how ultrasonic waves can be produced in the laboratory?
using ultrasonic interferometer
Which kinds of sound waves can be produced by bats?
Bats produce high frequency (also known as ultrasonic) sound waves, which they use as a type of sonar, to locate insects in the air.
What is the frequency produced by a 4-pole generator rotating at 1800 rmin?
60 Hz (Speed) x (#poles) = 120 x (freq)
What is the frequency produced by a 4-pole generator rotating at 3600 rpm?
f=P*N/120 f=Frequency in Hz P= No. of Poles N=Rotor Speed in Revolution per minute(rpm) for P=4 and N=3600, f comes out to be 120 Hz. So frequency of voltage produced is 120 Hz. But this is not practical. Generally 4-Pole generator has N=1500rpm(for 50 Hz) or 1800rpm for 60 Hz. Two pole generator can have N=3600rpm(f=60Hz). The most practical situation is generator having N=3600Hz with 2 Poles. Hope It will be helpful!!!
Introduction of ultrasonic?
we know that human ear can not hear sounds of frequency less than 20Hz or more than about 20,000 Hz . Sounds of frequency higher than 20,000 Hz , which are inaudible to human ear, can be produced and are utilized in many useful ways. Such sounds are called ultrasonics
Can an ultrasonic wave be produced by using speakers?
no Because ultrasonic sound waves are not audible and it is not possible to create that much loudness in normal speakers.
What is the relationship between the speed of a generator and its voltage and the torque on the generator shaft and the current produced by the generator?
emf produced by generator(E)=no. of turns in coil*rate of change of magnetic flux
Where is generator?
ATP is produced in mitochondria.
