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.
to connect the circuit
to get critical damped system
Michael Faraday did not invent or discover electromagnetism. After Hans Christian Oersted discovered it he simply studied it more.
Well, M. Faraday studied electromagnetism, and electromagnetism plays a big role in Lost.
a series resistence with its coil
What is the difference between the construction of a moving coil galvanometer and a ballistic galvanometer?
Its a point on the galvanometer where the galvanometer shows no deflection as no current passes through it.
Galvanometer that cannot die out oscillations instantaneously or quickly is called unstable galvanometer.
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.
The current is reversed in a galvanometer
because in tangent galvanometer earth magnetic field and magnetic field of magnet inside galvanometer are perpendicular to each other
galvanometer is a device use to measure current.
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.
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.
A galvanometer is used to test an electrical current. A galvanometer can be made using a compass and a thin gauge of wire.
The weston type galvanometer is a moving coil galvanometer in which a pointer is attached to the coil for measuring deflection due to torque .
A galvanometer is an instrument used for detecting electric currents.
