I need the answer of this question plz!!
Control transformer used only for control supply 110,220, 24,12V AC. But Potential transformer used voltage measurement purpose.
The difference between a current control device and voltage controlled device is that for current controlled device, the current is constant and the voltage is variable while for a voltage controlled device, the voltage is constant and the current is variable.
The flux control method is the convectional and the non-convectional method of speed control of an induction motor.
No. Use standard utility AC, 3 PH voltage to feed a Variable Frequency Drive (VFD). The VFD is then wired to the motor. The output of the VFD varies average voltage and frequency in a semi-constant proportion to keep Volts/Hertz ratio the same to the motor. The operator can then adjust or select the desired speed from the VFD and the VFD will run the motor continuosly at that desired speed. If you were to control only voltage to the motor without adjusting frequency in proportion, the motor would burn up.
it will control the flow of electrons between the source and drain,the controlling will be depends upon the input voltage to the substrate.
Potential meter is voltage control device and rheostate is current control device. it is a basic difference.
How many methods can be used to control the speed of Single Phase Induction Motor? 1.injecting emf method 2.by frequency control method 3.induced voltage method

what is the difference between a variable and a control
difference between feedback and control
Between power and control voltage circuits
The difference between a current control device and voltage controlled device is that for current controlled device, the current is constant and the voltage is variable while for a voltage controlled device, the voltage is constant and the current is variable.
Difference between control process and process control is that system control process is typically the large scale version of where process control is used.
Their is no Difference
The flux control method is the convectional and the non-convectional method of speed control of an induction motor.
you can control the speed of a motor by changing frequency, increase or decrease the field winding or by voltage regulation. in these method you can controle the speed of athree phese motor SANDEEP SARKAR
