How do you find the frequency of AC mains using Sonometer?
Measure the length of the wire AB between the edges of the two bridges and record it in ‘length decreasing’ column. Bring the two bridges closer and then adjust the length for maximum amplitude by increasing it. Measure the length and record it in length increasing’ column.
What is the frequency of AC mains?
Frequency of AC mains in India is 50 Hz,similar to most European countries. Whereas USA uses 60 Hz. Was this answer helpful?
Why AC current is used in Sonometer?
A sonometer is used to determine the frequency of alternating current. A step down transformer is used for the determination of frequency of A.C. because the voltage of the A.C. mains is 220V, which is dangerous. The step down transformer reduces this voltage to 6 volts.
What is Sonometer frequency?
Frequency of a sonometer is given by. f=2l1mMg , where l is the length an m is mass per unit length of the string. Frequency of the sonometer when the mass is immersed in water is. fw=2l1mMg−Vρwg . Here Vρg is the buoyancy force.
What are the applications of Sonometer?
A sonometer is a diagnostic instrument used to measure the tension, frequency or density of vibrations. They are used in medical settings to test both hearing and bone density.
How do you calculate AC supply frequency?
The frequency of the voltage is symbolized by f and given by f = 1/T. In terms of ω, f = ω/2π, in hertz.
What is Sonometer used for?
What is the frequency of dc power supply?
0 Hz
The frequency of direct current (DC) is 0 Hz, as the current only flows in one direction.
What is Sonometer and example?
A sonometer is defined as. The device that is used for demonstrating the relationship between the frequency of the sound that is produced by the string when it is plucked and the tension, length, and mass per unit length of the string. The sound is produced in the transverse standing wave in the string.
On which principle does the AC Sonometer work?
principle of Resonance
A Sonometer is a device based on the principle of Resonance. It is used to verify the laws of vibration of stretched string and also to determine the frequency of a tuning fork.
How do you change the frequency of an AC signal?
There are 2 ways of doing it: the hard way, and the hard way.
- Connect an AC motor for the input frequency to a generator of the output frequency.
- Rectify the input, then use a function generator of sorts with an H bridge.
What is a cycle in AC?
A cycle is one complete repetition of the sine wave pattern. It is produced by one complete revolution (360 degrees) of the AC generator.
How to find the frequency of AC mains using sonometer?
To find the frequency of the A.C. mains with a sonometer. Same as in Experiment 8 except a separate horse shoe magnet and a separate step down transformer. Let a loaded stretched soft iron wire have resonant length l 1 for the main frequency.
How to use an electromagnet as A sonometer?
Let the alternating current have frequency v so that the frequency of magnetisation of the electromagnet (V E) becomes 2v. Let a loaded stretched soft iron wire have resonant length l 1 with the electromagnet. Let a tuning fork of frequency V T have resonant length l 2. Place the sonometer on the table as shown in figure.
What is an AC sonometer?
What is an A.C. Sonometer? An A.C sonometer is an apparatus by which the transverse vibrations of strings can be studied. It consists of two bridges, near the ends, one horse shoe magnet at the middle and at one end is a pulley.
What instrument measures the frequency of sound?
Therefore, a sonometer is an instrument which measures the frequency of sound. Question.8.What is the unit of frequency of A.C.? Answer. Unit of frequency of A.C. is hertz (Hz) or per second. Question.9.What is frequency of alternating current supplied to us in our houses?
