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.

Galvanometer: An instrument for detecting and measuring small electric currents.
An electrodynamometer is a type of instrument used to measure electrical power or current, typically by utilizing the interaction of magnetic fields. A galvanometer, on the other hand, is a type of instrument used to detect and measure small electrical currents. In essence, an electrodynamometer can measure power and current, while a galvanometer is primarily used for detecting current.
A ballistic galvanometer measures charge by letting current flow through a coil and measuring the extent of its deflection. A deadbeat galvanometer is designed to quickly dampen the coil's movement to minimize oscillations, making it more suitable for accurately measuring steady currents.
The electrodynamometer was invented by Werner von Siemens in 1867. It is a type of instrument used to measure electrical power.
A galvanometer is a sensitive current measuring device that primarily indicates the presence and direction of current, while a voltmeter measures voltage in a circuit. Galvanometers typically have lower resistance and higher sensitivity than voltmeters, which are designed to measure voltage across a component or circuit.
To induce polarity in a galvanometer, you can connect the positive terminal of a power source to one terminal and the negative terminal to the other terminal. This creates a potential difference across the terminals of the galvanometer, inducing polarity in the device.
A galvanometer and a motor both have coils in a magnetic field, but they serve different functions. A galvanometer is used to measure small electric currents, while a motor is used to convert electrical energy into mechanical motion. The main difference is that a galvanometer typically has precise and sensitive measurement capabilities, whereas a motor is designed for generating rotational movement.

Power Factor of an electrodynamometer can be improved by connecting a large resistor in series with the current coil.
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.
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.
Well, darling, a galvanometer is a device used to detect and measure small electric currents, while an electric motor is a device that converts electrical energy into mechanical energy to produce motion. So, in simpler terms, one tells you how much juice is flowing, and the other one actually does the heavy lifting. Hope that clears things up for you, sugar!

Its a point on the galvanometer where the galvanometer shows no deflection as no current passes through it.
The current is reversed in a galvanometer
