How can a voltmeter be constructed using a galvanometer?
to connect the circuit
What does electromagnetism have to do with galvanometer?
A galvanometer is a simple meter that detects the flow of current. A current flowing in a wire causes magnetism around the wire. This is called electromagnetism. Like poles of a magnet repel and opposites attract. The Galvanometer uses these principles in order to move a pointer across a scale.
Why damping is small in ballistic galvanometer?
to get critical damped system
A moving coil galvanometer can be used as an ammeter by adding?
a series resistence with its coil
Convortion of moving coil galvanometrr into voltmeter?
A galvanometer can be converted into a voltmeter by connecting it with very high resistance.
What is the difference between the construction of a moving coil galvanometer and a ballistic galvanometer?
What is the difference between the construction of a moving coil galvanometer and a ballistic galvanometer?
What is a NULL Point of a galvanometer?
Its a point on the galvanometer where the galvanometer shows no deflection as no current passes through it.
What is unstable galvanometer?
Galvanometer that cannot die out oscillations instantaneously or quickly is called unstable galvanometer.
What is galvanometer and how a galvanometer converted into an ammeter?
A galvanometer is a type of ammeter an instrument for detecting and measuring electric current. A galvanometer can be converted into ammeter by connecting resistance in parallel with it.
Does a galvanometer have a reversed current or not?
The current is reversed in a galvanometer
Why tangent galvanometer is called tangent galvanometer?
because in tangent galvanometer earth magnetic field and magnetic field of magnet inside galvanometer are perpendicular to each other
What does a galvanometer measure?
galvanometer is a device use to measure current.
How you convert galvanometer into ammeter in detail?
By attaching a resistance in parallel connection with the galvanometer. Or when a low resistor connected in parallel with galvanometer ,the galvanometer is converted in ammeter. and the resistor is called shunt resistance.
How do you convert galvanometer to ohmmeter?
To convert a galvanometer to an ohmmeter an external battery is attached in series with galvanometer. This will drive a current through an external unknown resistance and measure the resulting current using the galvanometer.
Steps in making a galvanometer?
A galvanometer is used to test an electrical current. A galvanometer can be made using a compass and a thin gauge of wire.
What is weston galvanometer?
The weston type galvanometer is a moving coil galvanometer in which a pointer is attached to the coil for measuring deflection due to torque .
Function of galvanometer?
A galvanometer is an instrument used for detecting electric currents.
