What are the uses of Rheostat, Resistance, Ammeter, Voltmeter, Galvanometer, Plug Key, Battery Eliminator ?
Rheostat-
A rheostat can be used to change the current or the voltage across the current carrying straight conductor around which the patterns of magnetic field lines are studied. Change in voltage or current changes the strength of magnetic field produced by the conductor, which is essential in the study of the produced magnetic field.
Resistance:
Resistance is used in the circuit to reduce the current for our requirement and to increase the voltage drop for our purpose.
Ammeter:
The Ammeter is an instrument by which current is measured.It is always connected in series with the circuit in which the current is to be measured.
Voltmeter:
Voltmeter is an instrument which is used to measure voltage.It is always connected in parallel with the circuit.
Galvanometer:
The Galvanometer is an instrument which can detect the presence of electric current in a circuit.It is connected in series with the circuit.The presence of electric current can be detected by it's pointer which deflects depending on the direction of current.
Plug key:
A plug key works like a switch in a circuit.
Battery eliminator:
Battery eliminator is a device which is powered by electricity. A battery eliminator eliminates the need to replace batteries but may remove the advantage of portability. A battery eliminator is also effective in replacing obsolete battery designs.
