What is the difference between electrodynamometer and galvanometer?
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.

John Bardeen Walter Brattain and William Shockley invented the?
they invented the first transistor:)
What year was phonograph invented in?
The phonograph was invented in 1878. Thomas Edison invented it.
When was crescograph invented?
The crescograph was invented by Sir Jagadish Chandra Bose in 1901. It is a device used to measure the growth of plants.
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.
What will happen if the spring breaks in electrodynamometer?
there will be no control in the pointer hence it will show error in the readings

How is the torque produced in electrodynamometer unidirectional?
In an electrodynamometer, torque is produced due to the interaction between the magnetic fields generated by the current-carrying conductors and the fixed magnetic field of the permanent magnet. This interaction results in a force that acts in one direction, creating unidirectional torque. The design of the instrument ensures that the torque direction remains consistent, allowing for accurate measurement of AC and DC currents. As a result, the electrodynamometer effectively converts electrical energy into mechanical movement in a single, defined direction.
What are the types of electrodynamometer?
The two main types of electrodynamometer are attracted disc type and moving coil type. In the attracted disc type, two stationary coils create a magnetic field that attracts a disc attached to the moving coil. In the moving coil type, the coil is suspended between stationary magnets and experiences a force when current flows through it.
What are the different types of frequency meter?
The different types of frequency meters are :- 1. Mechanical resonance type 2. Electrical resonance type 3. Electrodynamometer type 4. Weston type 5. Ratiometer type 6. Saturable core type
Who invented the abacus when it was invented why it was invented and who invented it?

Explain Working principle of electrodynamometer type of instrument?
The working principle of a basic electrodynamometer instrument is same as the PMMC instrument. The only difference in this case is that the permanent magnet is replaced with two fixed coils connected in series. The moving coil is also connected in series with the fixed coils. The two fixed coils are connected to electromagnets in such a manner that they form poles of opposite polarity. As the moving coil carries current through it and is being placed in the field of fixed coils, it experience a force due to which the moving coil rotates. The direction of this force is independent of the supply voltage as the current flowing through fixed coils and moving coil is one and the same. If the direction of current changes in the moving coil, then the field direction also changes, thus making the torque unidirectional.
