Sonometer:

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.

Resonance: When the frequency of the applied force is equal to the natural frequency of the body, the body vibrates with very large amplitude. Corresponding intensity of sound will be maximum. This phenomenon is known as resonance.

A sonometer consists of a rectangular hollow wooden box called resonance box. resonance box
One end of a thin metallic ....etc

A sound level meter is a hollow wodden box used in the laboratory to study the transverse vibrations of the string. It is also called monochord because it often has only one sequence. In the rectangular box of wood there are two fixed bridges, near the ends, and at one end there is a pulley. A rope, often a steel wire is attached at one end over the bridges and pulley, and attached to a weight support that hangs below the pulley. Weights may be added to the support to cause tension in the wire, and a third movable bridge may be placed below it ....etc

basic avr working principle

Basically the AVR or Automatic Voltage Regulators function for generator is to ensure voltage generated from power generator running smooth to maintain the stable voltage in specified limit. It can stabilize the voltage value when suddenly change of load for power supply demand.
If the generator running in parallel condition,the AVR can controlled the voltage that it produce to ensure of equal value for reactive load sharing.
For the big system of interconnected power distribution with parallel design,it must have a ....etc

Our Objective:

To determine the frequency of alternating current using a sonometer.

The Theory:

A sonometer is an apparatus used to study the transverse vibrations of stretched strings. It is in the form of a hollow wooden rectangular box. On the wooden rectangular box there are two bridges and a pulley at one end. A wire string is attached to one end of the wooden box, run over the bridges and pulley and carries a weight hanger at the free end

A sonometer is used to determine the frequency of alternating current. A step down transformer ....etc

BASIC INSTRUMENTATION MEASURING DEVICES AND BASIC PID CONTROL


INTRODUCTION
Instrumentation is the art of measuring the value of some plant parameter,
pressure, flow, level or temperature to name a few and supplying a signal
that is proportional to the measured parameter. The output signals are
standard signal and can then be processed by other equipment to provide
indication, alarms or automatic control. There are a number of standard
signals; however, those most common in a ....etc

Physicslab Sonometer Viva Questions
01. What is the principle involved in Sonometer experiment?
Ans: Resonance
02. Which type of waves are produced in Sonometer experiment?
Ans: Stationary Transverse waves
03. What are transverse waves?
Ans: If the vibrations of the particles are perpendicular to the propagation of the wave, those waves are said to be transverse waves.
04. Which type of transformer is used in sonometer experiment and what is it?
Ans: Step down transformer. It is a device, which converts high voltage currents to low volt ....etc

Materials Required: A Resistance wire, voltmeter, ammeter, battery, rheostat, meter scale, one way key, connecting wires etc.

Theory: If I be the current flowing through a conductor & V be the potential difference across its ends, then according to Ohm s law
V I
or V = RI
Where, R is the constant of proportionality. It is known as resistance of the conductor.
V/I=R
R depends upon the nature of material, temperature & dimensions of the conductor.

Procedure:
1. Clean the ends of the connecting wires with the help of sand p ....etc
