Why is it important that the current in the coil of a motor changes with every revolution?
The current in the coil of a motor changes with every revolution to ensure continuous rotation and efficient operation. This change in current direction generates a magnetic field that interacts with the motor's permanent magnets or stator, producing torque. If the current did not change, the motor would stall as the magnetic fields would align and no longer produce the necessary rotational force. This principle is fundamental to the operation of electric motors, enabling smooth and sustained motion.
What else can I help you with?
The current in a what circuit is the same at every point?
A series circuit has the same amount of current at all points in the circuit.CommentIt's not simply 'the same amount of current at all points''; it's the same current at all points.
What is the formula for total current in a series circuit?
Current = (Voltage across the circuit) divided by (Total resistance of the circuit). The current is the same at every point in the series circuit.
What is Kirchoff's current law in electronics engineering?
Kichoff's current law says that the signed sum of the currents entering a node is zero.So, if you have a node with two wires, then the current on the first wire will exactly match the current on the other wire. If you have a node with three wires, then the currents will match up - lets say you had +2 amps on one wire and +3 on the second - the the third must be -5. (+n means current entering, -n means current leaving, that's why he said signed sum.An important consequence of this law is that, in a series circuit, the current at every point along that circuit is the same.
What is a rule for current flowing round a circuit?
In a series circuit, the current at every point in the circuit is the same. This is a consequence of Kirchoff's Current Law, which states that the signed sum of the currents entering a node must equal zero. Since a series circuit consists of nodes with only two elements connected to each node, it follows that the current at every point in a series circuit is the same.
What is the current of a series-parallel circuit connection?
The current flowing through a series circuit is (voltage between the circuit's ends) / (sum of all resistances in the circuit). The current is the same at every point in the series circuit.
Explain Why it is important that the current in the coil of a motor changes direction every time the coil makes a half revulotion?
due to commutation the current in the coil reverses
What is an example of conflict producing changes?
Every war or revolution in history has produced change of some kind, although the changes were not always improvements.
The split-ring reverses the sense in which the current is suplied to rotating coil after every half revolution?
due to comutator
Why is it important to understand that changes occur in patterns?
it is important because every thing has to occur step by step
Is the Earth's tilt and revolution the reason for the changes in the Earth's climate every year?
Yes, Earth's tilt and revolution around the sun are key factors in the changing of seasons, which in turn affects the climate throughout the year. The tilt causes different parts of the planet to receive varying amounts of sunlight, leading to seasonal changes in temperature and weather patterns.
A sentence using the word revolution?
The Earth turns one revolution every twenty-four hours.
Who is the governor of Nevada in 2011?
The governor of Nevada changes every couple years, but I believe that the current governor is Brian Sandoval.
What is the name of the current which reverses direction every half turn?
The current you are referring to is called an alternating current (AC). It changes direction periodically to allow for efficient transfer of electricity in power distribution systems.
Who are the permanent members of the United Nations?
The list changes every few years. Please see the accompanying link for the current list.
Why do you celebrate EDSA revolution?
EDSA revolution plays a very important role to the present bureaucracy and political system of the country.It is actually a manifestation of freedom,unity and nationalism of every Filipino to the country.
What is a frequency of ac signal in Pakistan?
The current which changes it direction after every half cycle is called alternating current(A.C) or Alternating current which produced by voltage source whose polarity keeps on reversing with time. By Shahnam qadeer
Why are rites of passage important for the Jews?
Rites of passage are important to every culture because they are the significant events that mark changes and growth in a person's life.
