What is the function of rheostat
Why should the generator field rheostat be kept to its maximum at starting?
Keeping the generator field rheostat at its maximum at starting helps to establish a strong magnetic field in the generator, which is essential for generating sufficient voltage to initiate the generation process. This ensures a smooth and stable startup of the generator.
Why motor rheostat kept minimum position generator rheostat maximum position?
the back emf increases so that high currents doesn't pass through the field windings
What are the problems of commutation in a DC generator?
1.resistance commutation 2.e.m.f commutation
Why it is called as logic function generator?
this generator operates using logical function thats why is called as logic function generator
Why the generator field rheostat kept at maximum position?
There is nothing to limit current until opposing magnetic fields build up at generator operating speed-windings will overheat and burn.
What is the purpose of field rheostat?
A field rheostat is used to control the current flowing through the field windings of a DC motor or generator. By adjusting the resistance, it alters the strength of the magnetic field, which in turn affects the speed and torque of the motor or the output voltage of the generator. This allows for fine-tuning of performance characteristics in various applications.
What is the function of rheostat in this experiment?
A rheostat is the name given to a variable resistor when it is used to control current. When a variable resistor is used to control voltage, we call it a potentiometer.A rheostat is connected in series with a load, and two of its three terminals are used. A potentiometer is connected in parallel with the supply, and each of its three terminals are used.So the terms 'rheostat' and 'potentiometer' are the names given to describe the function of a variable resistor, not the variable resistor itself.
What is difference between function generator and function generator?
To the untrained eye, they appear identical in both form and function.
Which xray generator is most efficient and provides the greatest signal intensity based on the same technical factors?
High Frequency
What is the function of a digital generator?
digital generator nothing but square wave generator or astable multivibrator
What is the purpose of a function generator?
A function generator creates electrical waveforms. The purpose is for developing and testing electric equipment.
