set up of the apparatus is arranged in circuit.ES is the standard e.m.f and Rs is the standard resistance of a cell.K1 is connected to position 1 and K2 closed.The approximation balance length is located.The jockey is tapped along a uniform wire until the G shows no deflection.K2 is then switch on the balance length is located accurately.The length ls is measured and recorded together with the ammeter. The procedure is repeated

How does sound change when using a slide on a trombone?
When you extend the slide it changes the pich which changes the note
What does the trombone have that other brass instruments do not have?
Unlike the rest of the brass family, trombones change notes by moving a slide instead of using valves.
How is the pitch changed on a trombone?
The pitch is changed on a trombone by moving the slide or changing your ombisture.
Which intrument used a U-shaped slide to change pitches?
All brass instruments (except the sousaphone) have slides. They are used to adjust the pitch, sharp of flat. The instrument that is played using a slide is the Trombone. It also has a slide on the back that is used to tune, or adjust pitch.
How do you get money out of a money box without opening it?
Sorry you can't, but you can try using a hard kitchen knife to kind of bent the lid to slide your money out.
What is the calibration of ammeter?
An ammeter should not be used as a voltmeter. An ammeter is a low impedance device that measures the current going through a circuit, often by measuring the small voltage across a known resistance. A voltmeter is a high impedance device that measures the voltage across a circuit. If you were to connect an ammeter as if it were a voltmeter, you would effectively short out the circuit, drastically affecting its operation, and potentially damaging both the circuit and the ammeter.
How do you measure voltage using a ammeter?
An ammeter measures amperage not voltage.
What must they do before using it?
calibrate it .
What is another term for potentiometer?
A potentiometer and a rheostat are two different applications for a variable resistor.A potentiometer is a variable resistor, connected (using its three terminals) as a variable potential divider.A rheostat is a variable resistor, connected (using two of its three terminals) to adjust current.
Experiments using potentiometer and error involved in those experiments?
yas
How do you find the unknown resistance by using potentiometer?
u mean potentiometer or a metre bridge ? 4 metre bridge R/X=L/(100-L)
How can find battry ampreas?
By using an Ammeter in series
What are the disadvantages of using ammeter and voltmeter?
The disadvantage of using a voltmeter and ammeter on circuit measurements is that internal burden in both these instruments can affect circuit operation so much as to make a measurement useless.
Electric current is measured using what device?
ammeter, which is understood as an amp meter
What is the equipment used to measure an electrical current?
Electrical current is measured using an ammeter.
What is a multi range voltmeter?
Multi-range ammeter using universal shunt
How do you calibrate compound gauges?
using master vacuum gauge and master pressure gauge
