What component of a motor changes the induced AC voltage into a pulsating DC?
The commutator is the moving part of the electrical switch in motors that reverses the current direction between the rotor and the external circuit. This is applicable in electrical motors and electrical generators.
What is the difference between impressed voltage and induced voltage?
Impressed voltage is the external voltage applied to a circuit, whereas induced voltage is generated within a circuit due to a changing magnetic field, typically caused by electromagnetic induction. Impressed voltage is controlled by an external source, while induced voltage is a result of the circuit's own dynamics.
Which law states that voltage is induced in a circuit whenever the flux linking the circuit is changing and that the magnitude of the voltage is proportional to the rate of change of the flux linkage?
Faraday's law of electromagnetic induction states that a voltage is induced in a circuit whenever there is a changing magnetic field that links the circuit, and the magnitude of the induced voltage is proportional to the rate of change of the magnetic flux.
What changes the flow of electrons in an alternating current?
first of all the voltage doesn't change what changes is the current direction the way they do it is by using magnet . electrons tend to escape from the magnetic field . you can find on you tube how a motor works for better idea.
Why does my 12 volt direct current motor stutter when i connect it to a pulsating 12 volt direct current power supply?
Your 12-volt direct current motor may stutter when connected to a pulsating power supply due to irregular voltage levels that prevent the motor from receiving a consistent flow of power. Pulsating DC can lead to insufficient torque, causing the motor to struggle to maintain its speed and leading to stuttering. Additionally, the motor might not be able to handle the rapid fluctuations in voltage, which can result in erratic behavior. To resolve this, consider using a stabilized power supply that provides a smooth, constant voltage output.
What component of a motor changes the induced AC voltage into a pulsating DC?
The commutator is the moving part of the electrical switch in motors that reverses the current direction between the rotor and the external circuit. This is applicable in electrical motors and electrical generators.
What is transistor series regulator?
voltage regulator is a component to convert pulsating DC into constant DC.
What does the resistance vs voltage graph reveal about the behavior of the electronic component?
The resistance vs voltage graph shows how the resistance of the electronic component changes with different voltage levels. It reveals the component's behavior in terms of how its resistance responds to changes in voltage.
Is induced voltage and induced currrent the same?
Induced voltage is alsocalled ghost or phantom voltage as if you apply a load it vanishes. induced voltage will be potential/electrical pressure. Amperage is the actual flow of current being used, Watts being its calibration of total power used.
Why do you think as the voltage across a lamp changes the power consumption?
Because the power of a resistive component is directly proportional to the square of the voltage across that component.
Why voltage induced when moving coil cuts flux?
The magnetic flux passing the coil changes by its rotation thus induced emf is produced and induced current flows
Do you add electrical supply voltage and induced voltage of a coil to get total voltage on the coil?
The induced voltage acts to oppose any change in current that is causing it. So, if the current is increasing, then the induced voltage will act in the opposite direction to the supply voltage; if the current is decreasing, then the induced voltage will act in the same direction as the supply voltage.
How can vary the induced voltage in rotor?
You can vary the induced voltage by varing the speed of the rotor.
What determines whether an induced current is a direct current or an alternating current?
There is no such thing as an 'induced current'. What is 'induced' is a voltage. The direction of the induced voltage is determined by the direction of the changing current that induces that voltage, because the induced voltage will always act to oppose that change in current. So, if the current is increasing, then the direction of the induced voltage will act to opposethe increase in current. If the current is decreasing, then the direction of the induced voltage will act to sustainthat current.
What is the unit used of resistor?
The ohm. It is how much resistance a component or part of a circuit has to the flow of electrical charge when a voltage is induced across it.
For voltage to be induced from one stationary wire to another one wire must have a n what type of current flow?
Intermittent. Faraday's law tells us that voltage can only be induced in a second coil when the current in the first coil changes
Who formulated a law for determining the direction of the induced current in a conductor?
There is no such thing as an 'induced current'. What is 'induced' is a voltage. If the conductor into which that voltage is induced forms a complete circuit, then a current will result. But it's the voltage that's induced, NOT the current! The direction of the induced voltage is explained by Lenz's Law which, in simple terms, tells us that the direction of the inducted voltage is always such that it will oppose the change in current that causes it. So the induced voltage will oppose any increase in current, but will act in the same direction as a reduction in current.
