∙ 12y ago
Electrodynamometer: An instrument that measures large amount of electric current by indicating the strength of repulsion or attraction between the magnetic fields of two sets of coils, one fixed and one movable.
whereas,
Galvanometer: An instrument for detecting and measuring small electric currents.

Difference between galvanometer and voltmeter?
Galvanometer is similiar to ammeter which is used to detect small current through it whereas a voltmeter measures the potential difference in a cicuit..
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
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.
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 .
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 the difference between the construction of a moving coil galvanometer and a ballistic galvanometer?

Difference between galvanometer and voltmeter?
Galvanometer is similiar to ammeter which is used to detect small current through it whereas a voltmeter measures the potential difference in a cicuit..
How is the power factor of an Electrodynamometer type wattmeter improved?
Power Factor of an electrodynamometer can be improved by connecting a large resistor in series with the current coil.
How does a electrodynamometer work as a voltmeter?
An electrodynamometer can work as a voltmeter by judging the wavelength and force of the electricity, much the same at the voltmeter, then converting it to a force that is more recognizable.
Does interchanging the galvanometer ad battery in a wheatstone bridge affect the balance?
No.AnswerWork it out, yourself, from first principles. Start with the assumption that, for the bridge to be 'balanced' (i.e. with no current flowing through the galvanometer), the potential-difference across the galvanometer is zero. It is quite simple.
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.
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 is one different between a galvanometer and an electric motor?
Electric motor is a machine that converts electrical energy to mechanical energy while a Galvanometer is an electrical instrument that measures small values of current.
