working principle of electrodynamometer is - when the same current passes through two concetric coils placed at right angles to each other,the resulting torque depends on the square of the current.
Electrodynamometer is used to construct various instruments like voltmeters,ammeters & also for constructing AC/DC wattmeters for any waveform of current & voltage.it is also used for frequency measurements & hormonic analysis.

Application of pulse width modulation?
PWM finds use in power applications like dc motor speed control
In what application does autotransformer starter use?
Applications:Used in both Synchronous motors and induction motors.Used in electrical apparatus testing labs since the voltage can be smoothly and continuously varied.They find application as boosters in AC feeders to increase the voltage levels.

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.
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
Why do you use labs?
for safety and for practical lessons
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.

What year did transistor radios out?
The transistor was invented by Bell Labs in 1948. Applications in consumer devices followed within a few years after that.
Did Stephen hawking visit bell labs?
Yes, Stephen Hawking visited Bell Labs during his lifetime. He was known for collaborating with various scientists and institutions, and Bell Labs, renowned for its contributions to physics and technology, was one of those places he engaged with. His visit highlighted the intersection of theoretical physics and practical applications in technology.
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.
