Why a single phase induction motor have two winding on stator?
Single phase motor will not start automatically unless it has a start and run winding.
What is the relationship between peak current peak to peak current and RMS current?
RMS is the root mean square value.(in alternating current only)
What is mean by magnetizing current of transformer?
A: As current flow in the primary it will magnetize the core of the iron in the transformer that is called magnetizing.
What does current focus mean?
it means that how are thing NOW.... what have changed.... how is it now
What current occupation mean?
What you are currently working as. Your occupation as in your job or profession.
How can you find the magnitude and the length of the resultant?
A ship is traveling 155mph due south .Opposing current 35mph at 20 degrees southwest . Find resultant magnitude and direction of ship's true course
Why it is that electron does not flow there is no current flowing?
Electrons are in random motion in a material, such that there is no resultant electron movement. Hence a material has no current flow by its own. Only the directed flow of this charge in a direction, will results in current. when we provide sufficient energy (for example by mean of applied potential difference ) the net motion of the electron gives rise to the current flow.
Why wattmeter measure the active power?
The wattmeter contains two coils one is current coil and other is pressure coil.the current coil is connected in series with the line and pressure coil is connected across the supply.so, the disc links with the flux which is the resultant of these two.(resultant means consider the vector resultant), which include phase angle also.the active power P=VI(cosine of angle between v & I).there fore the wattmeter measures the active power.CommentThere is no 'disc' in a wattmeter. Furthermore, the current coil doesn't measure the load current, it measures the in-phase component of the load current.
What is an antiresonance?
An antiresonance is a condition in an electric circuit containing a capacitor and coil in parallel and in which the alternative current line voltage and the resultant current are in phase, in which the impedance approaches infinity.
What is the angel when vector a is same as vector b and there resultant is same as given vector a and b?
If vector a and b are truly identical, their resultant angle will be the same. Their resultant velocity will not be the same, however. Assuming you mean the magnitudes are the same, the two vectors will be at an angle of 120o
Where is the resultant vector lies when dot product of two vector is done?
arithmetic mean
Is resultant a vector quantity?
The resultant of two vectors cannot be a scalar quantity.
How does voltage drop related to impressed emf?
Voltage drop is resultant of IR ie current and the line resistance, not dependent on impressed emf
What is the resultant velocity of a boat if it travels south across a river at 14 km per hr. It encounters a current flowing from east to west at 9 km per hour?
The resultant velocity of a boat is 17 km/hr and the direction of the boat is SW.
Which motion does a couple produce?
It has a resultant moment but does not have resultant force.
How to find resultant force?
To find the resultant force you need to find both the x and y component of the resultant force. Once you have that, you can use the Pythagorean theorem to find the resultant force.
Why Power factor becomes less lagging when capacitor is switched on?
Because capacitor withdraw leading current from source and net resultant become less lagging.
