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.

What is the difference between ballistic and a deadbeat galvanometer?
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.
Who invented the electrodynamometer?
The electrodynamometer was invented by Werner von Siemens in 1867. It is a type of instrument used to measure electrical power.
Difference between galvanometer and voltmeter?
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.
How do you induce polarity in galvanometer?
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.
How is a galvanometer similar to a motor how is it different?
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.

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.
How is a galvanometer similar to a motor how is it different?
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.
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
What is the basis of the function of a galvanometer?
The function of a galvanometer is based on the interaction between a magnetic field and an electric current passing through a coil of wire. When a current flows through the coil, it creates a magnetic field that interacts with a permanent magnet, causing a deflection of the needle on the galvanometer scale.
