What is power regulator?
A power regulator or a voltage regulator generates a fixed output voltage of a preset magnitude that remains constant regardless of changes to its input voltage or load conditions.
Why in slip test the machine voltage reduced?
The low slip test is used to determine the D and Q axis impedance of salient pole machines. The machine terminals are short circuited, each phase voltage and current are measured. Since the terminals are short circuited, machine voltage must be reduced to prevent excessive output currents that would damage the machine.
What is the special properties of a diode?
in the negative biasing it gives the constant voltage irrespective of limited current.......the voltage it provides in the negative biasing is known as 'zener voltage' due to this property zener voltage is used as voltage regulator........voltage regulator is a circuit which gives constant output even the input is changing.

What is 7815 voltage regulator?
A LM7815 voltage regulator is a component designed to maintain a constant voltage level, the LM78XX series of voltage regulators are designed for positive inputs and has the ability to drive the current within the circuit up to 1A. The component has three legs: Input leg which can hold up to 36VDC, a leg that leads straight to ground and an output leg with the regulated voltage. For maximum voltage regulation, adding a capacitor in parallel between the ground leg and the output leg will improve efficiency.
What will be the output voltage if reference voltage is short circuited in a series voltage regulator?
In theory it will be zero, in real life it's 0,003-0,005volts. Because the rule of ohm says: U = I * R. Shorted means that R = (almost) 0 so U will be close to zero too.
What is the difference of a fixed regulator from an adjustable regulator?
A fixed voltage regulator outputs only one specific voltage. An adjustable voltage regulator can be adjusted to output any voltage from the range it was designed for by changing the output resistors.
How does an alternator know how much voltage output?
Output of the alternator is controlled by the voltage regulator.
What does a dodge voltage regulator do?
It controlls the output voltage of the alternator.
How does a voltage regulator regulate the voltage output of an ac generator?
Generator output is controlled by voltage feedback to the voltage regulator which senses voltage drop or rise and regulates the current being sent to the armature. This rise and fall of the armature current governs the generators output voltage.
Is a potentiometer and voltage regulator the same thing?
No. A potentiometer is a variable resistor that allows you to set a voltage ratio or to adjust a resistance in a circuit. A voltage regulator, on the other hand, is a device that responds to changes in load, making automatic correction of output voltage. If you increase the load on a potentiometer, the output voltage will change, but not so (within limits) for a voltage regulator. However, you can use a potentiometer in a voltage regulator to make the output adjustable.
What is output short circuit current?
The output short circuit current is the solar cell's current when the voltage is zero, or when it, is short circuited.
What is the Function of an alternator regulator?
It controls the output voltage.
What is power regulator?
A power regulator or a voltage regulator generates a fixed output voltage of a preset magnitude that remains constant regardless of changes to its input voltage or load conditions.
How does a series regulator maintain the output voltage at a constant level?
A series regulator maintains the output voltage at a constant level by constantly changing the effective resistance of the pass device, usually the output transistor.
What happens when a regulator doesn't get enough volts?
A regulator loses some voltage in regulating its output, known as the dropout voltage. So the input voltage must be at least the output volts plus the dropout volts. If the input voltage is too low, the output will drop out of regulation.
What is an 7805 regulator?
7805is a voltage regulator integrated circuit. It is a member of 78xx series of fixed linear voltage regulator ICs. The voltage source in a circuit may have fluctuations and would not give the fixed voltage output. The voltage regulator IC maintains the output voltage at a constant value. The xx in 78xx indicates the fixed output voltage it is designed to provide. 7805 provides +5V regulated power supply. Capacitors of suitable values can be connected at input and output pins depending upon the respective voltage levels.Pin Diagram:Pin Description:Pin NoFunctionName1Input voltage (5V-18V)Input2Ground (0V)Ground3Regulated output; 5V (4.8V-5.2V)Output
