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.
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.
